Welcome to the Royal Dutch Shell 2018 quarterly results announcement. There will be a presentation followed by a Q&A session. If you have a question, please press star one. If you wish to be removed from the queue, please press star two. I would like to introduce our first speaker, Mr. Ben van Beurden.
Thank you very much. Ladies and gentlemen, welcome to the Shell second quarter 2018 results call. Of course, let's start with the disclaimer, with which I'm sure you are familiar. Today we are taking another important step towards the delivery of our world-class investment case with the launch of a $25 billion share buyback program. This move complements the progress that we have made since the completion of the BG acquisition back in 2016, to reshape our portfolio through a $30 billion divestment program, new projects to reduce net debt, and to turn up the scrip dividend. This quarter, our cash flow from operations, excluding working capital movements, is the strongest since the first quarter of 2014. The oil price, as I'm sure you all remember, was above $100 per barrel. Our financial framework remains unchanged.
Our free cash flow outlook and the progress we have made to strengthen our financial framework gives us the confidence now to start our buyback program, and our intention remains to buy back at least $25 billion of our shares over the period 2018 to 2020. That's, of course, subject to further progress with debt reduction and our price conditions. In today's call, I will first take you through Shell's performance across a range of critical areas, with updates on HSSE, portfolio, project delivery, and more. Jessica will cover in more detail our financial performance, the financial framework, and some highlights from our business. Before anything else, let me talk about our health, safety, security, and environmental performance. Nothing is more important than Shell. It is the bedrock on which everything else is built.
Goal Zero is our goal, zero harm to people or the environment, and this is critical for the responsible delivery of energy, and it is what society expects of us. We have to be known as a company that performs and behaves in the right way, and that does no harm to achieve any of our strategic objectives. This is true if you want to be a world-class investment case, but thrive through the energy transition, and it is true if you want to maintain a strong societal license to operate. The industry had a powerful reminder of the importance to have a relentless quest for improvement on HSSE earlier this month. It is now 30 years since the Piper Alpha disaster in the North Sea took 167 lives and turned many more lives upside down.
Shell, and the industry as a whole, have improved in many ways since then, but it would be a betrayal of the lives lost in July 1988 if we thought the work was now done. It's never done. If anybody is tempted to look backwards, admire the view, and say, "Hey, look how far we have come," I will always point forwards and reply, "Look how much further we have to go." You can see from this slide here that progress continues to be made in many areas in Shell. In 2017, for example, we had our lowest injury rate ever at 0.8 injuries per million working hours, and we continued to make progress on the environmental front. I'm not at all happy that we saw an increase in personal safety incidents in the first part of this year as well.
We have to keep working to improve our HSSE performance, even if much good work has already been done. I would like now to cover some of Shell's financial highlights from the first half of 2018. Our CCS earnings, excluding identified items for the first half of the year, were around $10 billion. Cash flow from operations was some $19 billion, and free cash flow was around $15 billion. All of this at an average Brent price for the first half of the year of $71 per barrel. Since the beginning of the year, we reduced net debt by some $4 billion, and gearing was 23.6 at the end of the second quarter. Return on average capital employed reached 6.5%. This performance builds on the strong financial results we delivered in 2017.
We came into 2018 with momentum, and we have maintained it with sustained performance and higher oil prices in the first half of the year. Let's move on and look at some of Shell's recent portfolio highlights. Recent portfolio announcements show the progress that we have made. In exploration, we announced two major discoveries in the Gulf of Mexico, Whale and Dover. We have also been successful in recent bidding rounds in Brazil and Mexico, and in July in accessing acreage in Mauritania. In our deep water portfolio, we took the final investment decision for Vito, one of our most competitive developments in the Gulf of Mexico, and for Gumusut-Kakap Phase 2 in Malaysia at the end of the year.
We also announced final investment decisions in our conventional oil and gas portfolio in the U.K. North Sea, with the redevelopment of the Penguins field and the development of the Fram field. Both of these are examples of how we are unlocking opportunities with lower cost. In the Netherlands, heads of agreement have been signed for the Dutch state to provide clarity on commitments and obligations with respect to the Groningen situation. During the quarter, we also started up two important projects. In chemicals, we announced the startup of our second cracker in Nanhai. Strengthening our position in China. In deep water, we announced the startup of Kaikias, a full year ahead of schedule. We're also making good progress in New Energies.
We announced the final investment decision for the 630 MW Borssele wind farm in the Netherlands, and we completed the acquisition of a 43.8% interest in Silicon Ranch, a solar energy developer with an existing portfolio of approximately 880 MW. Beyond the generation capacity, we have also strengthened our position at the customer facing end of the New Energies business with the acquisition of NewMotion, one of Europe's largest providers of charging stations, which we did at the end of last year. The acquisition of First Utility, a leading independent U.K. household energy and broadband provider. These developments are consistent with our strategy to develop a differentiated position in power.
We are building a low carbon offering that stretches end to end from customer all the way back to generation, and we are doing so by using the advantages we already have because of our existing power trading position, retail, and gas businesses. Finally, I should update you on how divestments continue to materially contribute to reshaping and simplifying our portfolio. This year we announced the sale of our downstream business in Argentina, of integrated gas positions in Thailand, New Zealand, Malaysia LNG and upstream positions in Norway and Iraq. In Iraq, we announced and completed sale of our stake in West Qurna in March, and in June we handed over operations of the Majnoon field to the Iraqi government. Since 2016, on a headline basis, we have completed $27 billion of divestment. We've announced another $3 billion and $4 billion are well advanced.
When we acquired BG, we announced our intention to deliver $30 billion in divestments before the end of 2018, and we will achieve that. In the Gulf of Mexico, we continue to strengthen our leading position. Today, we produce around 240,000 barrels of oil equivalent per day in the Gulf, and we expect to reach 400,000 by 2020. Our growth in this area is built upon our continued success in exploration, drilling improvement, project development, and operational excellence. In exploration, we announced two material discoveries, one in the Perdido area, Whale, and one in the Appomattox area, Dover. We also won nine blocks on the Mexican side of the Gulf. This acreage is nearly three times larger than our existing position in the U.S. part of the Gulf. These blocks are the equivalent of starting a whole new heartland in a single day.
The proximity and the technical similarity of these new blocks to our leading position in the U.S. Gulf of Mexico will allow us to benefit from and build upon 40 years of experience in the region. These developments are entirely aligned with our exploration strategy. Strategy is focused on near field exploration, filling our hubs, and seeking not only material volumes, but also short lead times between discovery and first production. Our most recent investment, Vito, will enter the construction phase with a forward-looking break-even price below $35 a barrel after we brought costs down by 70% from the original concept. Kaikias is another good illustration of our strategy. Approximately four years from discovery to first production. 30% cost reduction post FID, and as I already mentioned, first oil about one year ahead of schedule.
Appomattox has seen similar 30% cost reduction post FID, following the completion of the pre-drill campaign and the sail away of the facility for offshore installation in June 2018, the project is on track for first oil delivery in 2019. We're also making progress with operational excellence. Over the past two years, we have reduced unit operating costs in the Gulf of Mexico by more than 20%, and we are looking to improve this further. This year, we unlocked or restored more than 30,000 barrels a day of production by optimizing the performance of our existing wells, reservoirs, and facilities. Disciplined project delivery of the sort that I outlined in the Gulf of Mexico is an important part of our growth strategy. There are two important milestones which show our progress in this area.
The first is our Nanhai joint venture with CNOOC in the Guangdong province, which I mentioned briefly earlier. There we have completed the startup of a new ethylene cracker and ethylene derivative units. These new facilities increase the ethylene production capacity of the joint venture by more than 1 million tons per year. That's roughly doubling the previous capacity. The project also includes a styrene monomer and propylene oxide plant, which is the largest of its kind ever built in China. For the second milestone, I would point to Prelude, our floating energy facility in Australia. We successfully imported LNG to Prelude in June, followed by a successful import of LPG into the facility. This means that the facility is now live. With LNG and LPG on board, the Prelude team can now start testing processes and systems before the subsea wells are opened.
The offshore team is preparing for that moment, getting the seven wells tied to the facility and ready to flow. Based on our current commissioning schedule, we are on track to start production this year. You can see from this slide how our progress with reducing our expected unit development cost and project breakeven prices is feeding through into a portfolio of competitive options in upstream. Our discovered resources represent more than 20 years of production. Importantly, we are continuously improving the competitiveness of these opportunities. Upstream forward-looking breakeven prices for most new projects are now around $40 per barrel or below. We are embedding these lower development costs to make sure that they are a structural feature of our portfolio. This means lower costs that go far deeper than the attractive market conditions we have seen in recent years with contracts.
This is Shell's driving long-term improvements to the bottom line through a program of deliberate self-help and discipline. Of course, project delivery is nothing without cash delivery, and we have a powerful story to tell here as well. As you know, we expect new projects delivered since 2014 to generate $10 billion additional cash flow from operations by the end of 2018, and $15 billion by the end of 2020, at $60 per barrel real terms 2016. The first half of 2018, we have delivered an estimated $5 billion, and I'm confident that we will deliver $10 billion by the end of this year. We remain on track to deliver our 2020 organic free cash flow outlook of $25 billion-$30 billion or $50 billion-$60 billion cash from operations, and that's excluding working capital. All of that at $60 per barrel real terms 2016.
Jessica will cover our financial framework in more detail shortly. I would like to introduce this topic by repeating again our commitment to the capital discipline. We remain firmly committed to our $25 billion-$30 billion capital investment range. I can confirm that we continue to expect investment to be in the lower part of this range in this year, 2018. Also for the avoidance of doubt, this range includes all capital investment, organic and inorganic. Discipline makes sense not only from a financial point of view, where you can see that we have made real progress with strengthening the balance sheet of the company, but also from a strategic and portfolio point of view. In fact, consistency in our investment program through the cycle is critical if we are to deliver competitive returns. It enables disciplined capital allocation, greater capital efficiency, and counter-cyclical investment.
As you know, we completed the BG Group acquisition when the oil price was in the 30s. We have continued to invest steadily since then. Since 2015, we have maintained capital investment around $25 billion, which is an industry-leading level. Our clear and consistent investment and capital allocation strategy has positioned us well for growth. That is why we do not feel the need to catch up by accelerating capital investment beyond the $25 billion-$30 billion range. As I said earlier, today we announced the launch of our share buyback program. I'm sure that you are as pleased to hear it as I am to announce it. There could be no better time for me to reemphasize the importance of shareholder distributions in our financial framework. Since 2016, we have distributed more than $38 billion in dividend, of which more than $28 billion has been in cash.
Over the same period, we have delivered more than 85% total shareholder return. That's an industry-leading performance. An attractive dividend is obviously a critical part of our world-class investment case and achieving competitive total shareholder returns. The share buyback program will not only add to our total shareholder distributions, but also reduce our share count to provide additional growth in our financial metrics on a per share basis. Of course, over time, a lower share count also means a lower dividend payment, and therefore more flexibility in our financial framework to respond to the prevailing oil price environment. Let me hand over to Jessica. She will cover the financial framework and the Q2 results in more detail.
Thank you very much, Ben. The pillars of our financial framework remain unchanged. Firstly, a strong balance sheet. We aim to achieve AA equivalent credit metrics through the cycle, for which gearing is a proxy. At this point in the cycle, we think that 20% is adequate, though we expect to go lower than 20% as we continue to reduce net debt over the coming years. Secondly, maintaining an attractive U.S. dollar dividend per share. Thirdly, distributing surplus free cash flow to shareholders in the form of share buybacks. The announcement of the share buyback program today shows that we are confident that 20% gearing is within reach based on expected organic cash flow and divestment proceeds, that we are firmly committed to capital discipline through the cycle, and that we have confidence in our 2020 free cash flow outlook.
Our financial framework has not changed. Our cash flow priorities have not changed either. We're progressing to 20% gearing. We removed the scrip in Q4 2017, and we generate enough cash to cover the dividend. We're confident that our cash generation and continued divestment proceeds in the coming years will be sufficient to allow us to reduce debt and deliver AA equivalent rating metrics while using additional free cash flow to buy back shares. We want to deliver on our financial commitment in a disciplined and predictable manner, even though the actual pace of delivery might vary from one quarter to another as a result of performance or external factors. Let us have a closer look at our financial performance at the end of Q2 2018 on a four-quarter rolling basis.
At an average oil price of $64 per barrel, CCS earnings, excluding identified items, amounted to $18.5 billion. ROACE on a CCS basis, excluding identified items, was 6.5%. ROACE is expected to continue to improve towards our outlook of 10% in 2020 as we continue to reshape our portfolio, start up new projects, and improve performance and capital efficiency. Cash flow from operations, excluding working capital, amounted to $40 billion. Our organic free cash flow was close to $13 billion. Over this period, we distributed almost $16 billion in dividends to our shareholders, of which $13 billion has been in cash. Since 2016, we've received close to $26 billion of cash proceeds from divestments in our MLP, with close to $6 billion this quarter alone.
The successful delivery of our divestment program has allowed us to reduce gearing from almost 30% in 2016 to less than 24% this quarter. It gives us line of sight to further gearing reduction. Let us move to the results of the second quarter. Our Q2 2018 CCS earnings, excluding identified items, were $4.7 billion, which is $1.1 billion, or 30% more than in Q2 2017. Earnings, excluding identified items in upstream were more than four times, or $1.1 billion, higher than in Q2 2017, driven primarily by higher oil prices. Production was 7% lower than in Q2 2017, largely as a result of divestments. Excluding divestments, production was up 2% over the same period.
In our integrated gas business, earnings excluding identified items increased by $1.1 billion, or 97%, compared to Q2 2017, as a result of higher prices, a particularly strong contribution from trading, and higher LNG sales volumes. Production was 16% higher than in Q2 2017. In downstream, CCS earnings, excluding identified items, were $0.9 billion, or 34% lower than in Q2 2017, driven by lower trading results, higher operating expenses, and adverse exchange rate effects. Growth in marketing was partially offset by lower retail margins as a result of higher crude prices and price caps in some markets. Overall, we saw a 5% increase in operating expenses since Q2 2017. A large part of this increase is driven by foreign exchange and portfolio effects. Our focus on cost reduction and efficiency gains remains unchanged. We see further potential to reduce our operating expenses.
Another point to highlight is the particularly notable impact of differences in exchange rates this quarter. The appreciation of the dollar reduced earnings, excluding identified items, by close to $300 million, with an additional associated tax impact of close to $200 million. Cash flow from operations in the quarter was $9.5 billion, and excluding working capital movements, this was $11.6 billion. As Ben mentioned, this is our strongest level of cash generation, excluding working capital, since Q1 2014, when oil prices were above $100 per barrel. Cash flow from operations was reduced by $800 million in relation to cash margining on our hedging program in Integrated Gas. The working capital movement of $2.1 billion was largely driven by the price impact on inventory. In addition, cash tax payments were impacted by an agreement with Shell that Shell signed with the government of Oman this quarter.
This agreement results in a changed phasing of tax payments. Upstream cash flow from operations is expected to be impacted by higher tax payments of approximately $500 million for the full year 2018, of which more than $100 million were paid in the second quarter, and a further $500 million for the first quarter in 2019. This will be followed by reduced payments in the subsequent four years. Let's move to a few highlights from our businesses. In our Downstream business, it has now been over one year since the completion of the Motiva separation. We are seeing some real tangible benefits from that separation. We are identifying and capturing additional value through the integrated approach we are now able to take across our Downstream assets in the U.S. Gulf Coast. For example, we decided to continue operating the Convent cat cracking unit quickly after the dissolution of Motiva.
This decision was based on an integrated value analysis of the Louisiana and U.S. Gulf Coast markets. Value is generated through additional refinery margins, but also through integration with Norco chemicals operations and with trading. We expect to have a payback of approximately one year on the costs associated with this decision. At Deer Park, we've decided to improve the crude flexibility of the refinery. This will allow us to take full advantage of Shell Trading's global reach and access to a wide range of crude and feedstocks to deliver additional value. Other examples include the better integration of trading and supply with retail and distribution in the northeast of the U.S. Now we can also better integrate our plant in Mobile with our marketing activities in this area, which was previously a Motiva marketing territory. We expect around $50 million per year additional gross margin from the stronger integration.
In Integrated Gas, we're expected to take a go, no-go decision on LNG Canada this year. As you know, we expect a supply gap in the LNG market in the early 2020s. We have an attractive portfolio of new supply options, including new projects, expansion of existing projects, and third-party supply opportunities. We want to select the most competitive source of supply. LNG Canada is the most mature of these options. The strategic benefits of the project are well established. LNG Canada has access to abundant and low-cost gas at a short shipping distance to North Asia. It also has lower greenhouse gas emission intensity than any comparable operating LNG plant. We now have a clear view on construction costs, as the joint venture has awarded a conditional lump sum contract for the engineering, procurement, and construction of the project. In short, LNG Canada looks very promising.
Together with our partners, we need to finalize consideration of a few key items before we can take a positive final investment decision. Firstly, affordability. We know that the funding of our share of the project fits within our existing capital ceiling. Secondly, competitiveness. Can the project deliver LNG to North Asia at a cost that is competitive with LNG projects in the Gulf of Mexico? Thirdly, resilience. Will this project generate positive free cash flow across a range of commercial and energy transition scenarios? Lastly, attractiveness. How does this project compare against other investment opportunities over a similar time span? As you can see, we are taking a very disciplined approach and are being thorough in our evaluation of LNG Canada, as we are with all of our major investment decisions.
We see great opportunities, but we also have clear expectations when it comes to competitiveness, affordability, and returns. In Upstream, I would like to highlight how we have significantly improved our shales business in the Permian. After significant restructuring between 2013 and 2015, we have adjusted the delivery model of this business with a strong focus on competitiveness and value. Our Permian asset has delivered significant growth to date, achieving some 85% production growth since 2016. We expect production to grow more than 30% annually through 2020 with similar levels of capital investment. We are actively developing our 260,000 net acre position in the Delaware Basin and have been enhancing our position with swaps, allowing us to consolidate our blocks and further optimize our development plans. Delivering this potential will yield strong free cash flow growth well into the next decade.
As I've already touched on, we are developing the Permian following an improvement in cost competitiveness. For example, we have reduced drilling and completion costs for new wells. We have realized an overall 40% cycle time reduction in our well delivery process since 2017, and we expect we can still do more and reduce costs further despite supply chain pressures. We are confident that we can deliver strong organic growth from our shales business. In addition, the integration with our trading business allows us to maximize the value from our barrels. Before I hand back to Ben, let me return to where I started. We remain committed to our financial framework, and further debt reduction remains a clear priority. Our 2020 cash flow outlook is strong. We have excellent growth opportunities in the 2020s. Shell's future is bright, and we remain prudent and disciplined.
With the launch of our share buyback program, we are taking another firm step towards transforming the company into a world-class investment case.
Thanks, Jessica. Today we announced the launch of our share buyback program, the decision is founded on our strong performance track record, our cash-generating outlook, and strengthened financial framework, our unchanged commitment to capital discipline, and our rigorous capital allocation. Of course, our strong confidence in the longevity and the competitiveness of our portfolio. We are delivering on our commitments. Now with that, let's go to questions. Please could I have just one of two questions from you each so that everyone has the opportunity to ask a question in the remaining time? Operator, can I have the first question, please?
Thank you. We'll now begin the question and answer session. People dialed in, if you have a question, please press star or one. If you wish to be removed from the queue, please press star two. We'll go first to Oswald Clint with Bernstein.
Hi. Good afternoon. Thank you. My first question was really on the integrated gas earnings, which I guess in the first half of 2018 are almost double what they were the same time last year. Obviously, oil prices explain a little bit of that, plus Gorgon. I want to know, was there any information or color you can give us on where you're selling the bulk of these LNG cargoes these days? Has there been any noticeable shifts or mix change in the countries? Is this more and more of Shell's cargoes going into China, kind of relying on that strength in Chinese LNG import demand continuing? Does it pose a particular risk if that was to end some point in the future, or is it across most of the Asian countries?
I guess if it is more and more balanced, you spoke about B.C., Canada, shouldn't you be really telling us about more LNG projects coming through the development queue? That's the first question. Secondly, Jessica, you mentioned North American shale restructuring. I look at the second quarter North American Upstream earnings, it looks like one of the highest earnings you've done in at least the five years. I guess your blended realizations are pretty flat year-over-year. I guess it's hopefully evidence that you have really taken on some of the cost base of that particular onshore U.S. business. I really just want you to confirm that if I interpret it that way, it's evidence to show that the costs have lowered within that North American shales business. Thank you.
Okay, thanks very much, Oswald. Two very good questions, I think both for Jessica.
Right. Indeed, IG had another, dare I say, fabulous quarter. A very strong first quarter and followed by a very strong second quarter. It reflects a number of things. First of all, the overall production for the business, gas production, is up 16%. The business is growing with Gorgon coming on stream, but importantly also bringing more feedstock into MLNG and into Trinidad as well. Our utilization rates across the portfolio have been increasing over the year as well. Indeed, the market conditions have been good. The trading conditions have been good. We saw some very high prices in Mexico that we're able to secure cargoes going into. Across the portfolio, good performance, good trading conditions.
Indeed, China demand continues to be strong and we continue to provide supply, as you see with our underlying liquefaction volumes going up, but also our LNG overall volumes going up as we also pick up spot cargoes to take advantage of good market conditions. Indeed, I think it's well said in terms of what you're seeing happening in our North America business. Of course, that is both our shales business and our deepwater business performing very well and coming through in those earnings numbers that you're seeing. Both of those business have done an exceptional job of driving capital efficiency. You hear the stories of Vito, of Kaikias, and the piece that I gave on the unconventionals business in terms of wells and completion costs.
Great capital efficiency story, but as you said, also a very strong operational expense story where our operating costs in both of those businesses have declined over the last couple of years. All of that contributing to what you're seeing in terms of positive earnings in our North American business.
Okay. Thanks, Jessica. Thanks, Oswald. Can I have the next question, please?
Well, the next to Jon Rigby with UBS.
Yeah. Hi, thank you for taking the questions. Just a couple. The first is on operating cash flow. Am I right if I do a quick bit of mathematics, is that if we were to take the bottom end of your implied free cash flow range and then work that through to operating cash flow, at $75, you probably should be generating $13 or $14 billion of operating cash flow against the 11.6x working capital movements. I sort of look at that in the context, I think the comments that you made about additional $5 billion of cash flow performance improvement coming through in the second half of the year.
I wonder whether you could go into a bit more detail about what are the things that have to happen over the next 18 months or so, 12 to 18 months or so, to get us into the range of implied operating cash flow that you've talked about, if my arithmetic is correct. The second is, I think, Ben, you talked about one of the main issues on creating the world-class investment case was to create predictability and visibility around earnings.
I just wonder whether there's been a pause for thought around that, given Jessica had to do a lot of work at 1Q explaining some one-off items and reference the fact that she'd had to do the same at 4Q, it feels again at 2Q that you're having to do the same thing to explain earnings that I think if I look at expectations are somewhat disappointing. I just wondered whether there's more work to do on the predictability of the performance of the business. Thanks.
Yeah, thanks for that, Jon. I'm sure that Jessica will want to talk to both questions, but let me have a first go at the second one as well. Yes, of course, you're absolutely right. Predictability really helps. We know that very clearly. I think we have been doing quite a bit to also have better disclosure that will help. Indicating a little bit better how things flow through our earnings statement. Getting a number of things out of clean so that you have a better understanding how what is, after all, a very elaborate and complete portfolio with a wide range of businesses in a wide range of countries subject to lots of macro effects, hopefully gives a little bit more insight. Having said that, much though I would love to have completely flat earnings, or at least linearly going up, we don't manage for earnings.
We don't manage for results. We manage for value. Some things will fall in a certain way. There is not much we can or want to do about it. Therefore, there is a certain amount you will have to take, and we will have to take as well. Bear in mind also that, of course, we've been in the middle of a very significant portfolio restructuring and upgrading program, which of course also throws a number of changes off, both on balance sheet, but also flowing through to P&L. That's another thing to consider. Jon, I'm well aware that sometimes our results in some quarters can be hard to get right because there are things that are invisible to you. I'm very mindful that is uncomfortable, and that we have to do whatever we can to give you more insights.
Where we can, where it actually makes value sense, avoid that. I'm sure that Jessica has more to say on this particular quarter, where some of the perhaps unexpected earning effects came from, but then also give you a bridge to the free cash flow and operating cash flow for the end of the decade.
Jon, thank you for the questions. Building on what Ben said, indeed, the preference is to deliver consistent, reasonably predictable earnings, and for those earnings to be growing over time. That's certainly what we're trying to drive in terms of underlying performance of the business. Accounting is not always easy to deal with. Macro effects such as FX can also bring noise into the numbers. I wish that weren't the case. We're certainly trying to drive as much transparency in terms of what's causing these effects as we can. We had one of the most rapid appreciations of the dollar against most currencies around the world in the last quarter. It was up some 16% against the Brazilian real. That's one of the fastest ramp-ups there has been. With the nature of our business, that is going to flow through our financial statements.
What we can do is provide transparency on that. We can't predict where FX will go, at what pace it will change, but we can certainly explain what's happening to our business because of FX effects. That's certainly important for the quarter. That was some $600 million, $700 million of the impact on earnings for the quarter. That impacted our corporate segment. It impacted our downstream business as well as our upstream earnings as well. As Ben mentioned, divestments is another piece. As you remove $30 billion of assets and entities from your financial statements, there's all kinds of accounting implications around that. Again, we try and bring the right level of transparency. Some of that should smooth out as we close out that program over the coming months. There'll be some amount going on in the future, but certainly not at that pace.
I think a couple other elements to talk to for the quarter that also speak to the cash. Another piece of the puzzle from an earnings as well as a cash perspective is what was happening in terms of realizations and importantly, differentials in North America. While Brent was up 50% year-on-year, WTI was up only 40%. There was a widening between WTI and Brent, and that certainly had an impact on our business in North America. Importantly, Henry Hub was down 70% and AECO was down 53%, and we're selling gas into both of those markets. If you just use the rule of thumb and those considerations of some of the potential differential effects weren't taken into consideration, that's another some $200 million that was impacting both earnings and cash for the quarter.
In terms of the bridge of where we are today and what the business is generating and our confidence in getting to the $25 billion, couple of things there. Rolling 4-quarter basis, last 12 months, our organic free cash flow was some $13 billion. Working capital effects over that period was some $6 billion. Margining effect was some $2 billion. Then we're having significant ramp-up of projects that are already on stream that will start continuing to happen through the fourth quarter. Importantly, new projects will be coming on stream over the next couple of years. That will bring another further $5 billion-$10 billion between now and 2020. All in combination, that gets you from where we are today and why we have confidence in terms of our ability to deliver on the $25 billion-$30 billion organic free cash flow ambition for 2020.
Okay. Thanks, Jessica. Thanks, Jon. Good questions. Can I have the next question please, operator?
Yes. We'll go next to Thomas Adolff with Credit Suisse.
Hi, good afternoon. Hi, Ben. Hi, Jess. I just want to start with the mid-year report. I had mine earlier this week, and just wanted to focus on two areas, namely working capital management and refining and trading. How can one do a better job managing the working capital? It's been a big drag for the past four quarters, about $6 billion or more than that. That's $10 to your break even. Your competitors are not seeing such a drag from a working capital. I wanted to get a bit more insight into how you can do a better job here. Secondly, just on refining and trading, again, the past three quarters, either I'm just modeling it incorrectly or something is happening here. What happened to the magic of capturing the margin whereby it rises, which also in turn reduces the earnings volatility?
Is the machine working according to plan? Then I guess just a quick question on LNG. You've highlighted there's a supply gap potentially in the early 2020s, which kind of means for greenfields, it could be too late, and the brownfields will have to fill the gap. I'm just wondering if you're looking at any brownfields within your portfolio or backing some other brownfield projects funded by other companies. Thank you.
Thanks, Thomas. Then I'm sure Jessica will add to it and also talk about working capital. I think large greenfield projects now will come into the window when we expect there to be a significant shortfall between actual supply and implied demand. I'm sure if we were to go ahead with some of these greenfield projects, we will enjoy them. You're absolutely right. We need to do other things as well to capture as much of it as possible. Brownfield projects are great opportunities to do so. As Jessica already mentioned earlier on, we have had a lot of focus in the last few years, particularly after the BG Group assets came in, to really understand how we can improve utilization of existing LNG supply chain.
That is working out. We're now also at a point that we are looking at a number of debottlenecking opportunities in LNG plants around the world. One of which, I think has been in the news recently, which is Nigeria LNG, where we just entered into the sort of FID phase and hopefully, if not late this year, probably more likely next year, we will be in a position to consider sanctioning that expansion. Yes, absolutely, we are intent on capturing whatever we can by making sure that our assets and supply chains are full and that we sweat or expand assets where we can. I think refining and trading, if you look at the performance and you compare the performance that we have seen in our refining and associated trading business against the margin that is available, we have actually outperformed the market.
Granted, the refining margins have been weak. Breaking it down, what was available, we have captured and did better than that. While we are on downstream, can I also add that we had a very strong performance in our marketing business, in a rising market where we always have, of course, the effect of margin compression. Bearing in mind that we had quite significant curtailments on margins in places around the world, in Indonesia, in Turkey, in Argentina, disruptions in Brazil, we have managed to find offsets for that. Our marketing business has performed very well in a different set of circumstances. Let me hand over to Jessica to perhaps give a bit more color on that, certainly also to cover the working capital element.
Thank you. We have a large profitable trading business that allows us to create more value across our integrated value chains, whether it's downstream or integrated gas. Frankly, our upstream business as well. That's not to say that every quarter we're hitting it out of the ballpark. Through the cycle and through time, it has proven to be, I think, key to our strategy and key to our delivery is that trading capability that we have in the organization and maximizing value across those value chains. With that, particularly for our downstream business, we have a large inventory of barrels that we use. It's a key element of getting value from our trading operations. In the last year, the volume of our barrels have come down some 10%-20%. It's not that we've been increasing our volume exposure. It's entirely a price story.
The price that we've used to value the inventory on our balance sheet has gone up by some 50%, and that's really driven approximately 90% of the increase in working capital that you're seeing for the quarter. It is a function of our strategy, in terms of using inventory, trading around it. What I can say is that we have a very intense and effective management system in place in terms of choosing what our working capital levels should be. It's driven by a view on risk and return. It gets a lot of attention by management to ensure that we are making the right choices around inventory levels and working capital. There's specific return requirements that the business needs to deliver on. The outcome of our working capital is by deliberate choice. We can't always identify the price that the quarter end will land at.
What you're seeing is really a price effect, but underlying that, it is based on our strategy and specific management choices in terms of the working capital that we're carrying.
Okay. Thanks very much, Jessica. Thanks, Thomas. Can I have the next question, please?
Thank you.
We'll go next to Martijn Rats with Morgan Stanley.
Yeah, good afternoon. It's Martijn here. I wanted to ask you two things. First of all, reading your outlook statement with regarding to production for the third quarter. It looks relatively weak with both a quarter-on-quarter and year-on-year decline. If you sort of relate that to the amount of net debt in the firm, I think it's fair to say that the balance sheet is de-gearing, but over the last year or so, the de-gearing has been somewhat slower than we, for example, would have modeled a year ago. If you look at the ratio, sort of net debt to production, sure, the balance sheet is de-gearing, but net debt per barrel produced, and I know this is a somewhat esoteric metric, but it's somewhat interesting nonetheless. Net debt per barrel produced is actually sort of hardly falling.
I know you're sort of saying, well, sort of remain on track for sort of free cash flow guidance that you sort of given. I was wondering, is this really sort of on track with the plan as you sort of had it maybe a year and a half ago? Somewhat related to that, the second thing I wanted to ask you is that I think the buyback program is of course very welcome. We're all sort of waiting on that. The figure of $2 billion over the next quarter is a somewhat intriguing one in the sense that if you simply divide $25 billion over the remaining 10 quarters between now and the end of 2020, you would get to an implied run rate of USD two and a half billion a quarter.
I don't want to read too much into what might simply be a rounding error, but nevertheless, it sort of suggests that the buyback is starting, but not quite at the rate that is implied by the overall program. It's still starting in a fairly cautious manner, and I was wondering how that relates to the statement around confidence in free cash flow at the disposal of the balance sheet that you also talked about.
Okay, thanks, Martijn. I think Jessica is rearing to answer these questions, and I'm sure I will have an add to it as well.
Good. Thank you, Martijn, for introducing yet a new metric in terms of how we think about our business. The gearing to production ratio is not one that I've considered before. I think that the main message from this quarter and from the share buyback program is one around confidence in the underlying performance of our business and the cash flow generation over the next two and a half years. It's a challenge to kind of run the business and have all the metrics work quarter on quarter every quarter and predict exactly what it's going to look like. It's a big, dynamic business, so I think focusing on the trajectory and the very clear numbers we've provided around our organic free cash flow, getting to $25 billion-$30 billion by 2020, achieving the buybacks of $25 billion by 2020, and bringing gearing down to 20%.
All three of those things we're looking to make true through the next two and a half years. It's dynamic in terms of how cash flow moves, how working capital moves, et cetera. I think you should be reading in what we're announcing today and the amount we're announcing and recommitting to the $25 billion, that is the trajectory we're on. It's, I think, looking through the quarters and not focusing on any given one quarter is the right thing to do. We're comfortable with the cash flow. We're comfortable with where our production is. We knew there'd be a change in the production profile with the divestment program.
That's happening, but we're also growing, and the underlying business of upstream increased by some 2% if you take the divestments out, and there's a number of new projects that are coming on stream that will add another 700,000 barrels of oil equivalent over the coming years. So that ramp up with Appomattox coming on stream, with Prelude coming on stream, et cetera, there'll be new growth in the portfolio that's going to support cash flow generation and underpin the numbers we've provided.
Thanks, Jessica. Martijn, I think Jessica said it all, but I think it's also important that I underline this myself as well. Of course, we look at every quarter and understand what's happening. We also look, of course, multiple quarters ahead to really understand what is going to happen given a certain amount of macro scenarios that we can envisage. We've been very clear, I have been very clear personally, that we want to have a track record that is credible, that we deliver on our promises, that we do the things that we talk about with discipline, and with it, of course, a certain degree of prudence because we do not want to get ahead of ourselves.
You have to hopefully also give us some credit for the fact that we have delivered on all our promises and have every intention to deliver on this promise as well. And with that will come a fair degree of scrutiny of what we think the future has in store for us when we commit or launch a buyback program that, of course, will be scrutinized quite considerably over the quarters to come. Again, I completely underscore the points that Jessica made, that we are at the point where we think we can and need to do this, and we have the confidence that we can see it through. Can I have the next question please, operator?
We'll go next to Christyan Malek with JP Morgan.
Hi, thanks for taking my question. Just the first question is on the line cash flow evolution, so to harp back on this, and second question is on the buybacks again. First on cash. I come back to the question I've asked on the previous calls, and I was hoping to see an improvement in the cash flow capture at higher oil. Yet underlying cash break-evens have moved sideways around the mid-60s. Meanwhile, compared to a year ago, and I think the point was made by Jon, Shell's cash flow from operations is down 16%, despite oil being up 50%. I understand the impact of divestments, quarterly variances in taxes, working capital and derivatives or higher oil. What I don't understand, or I want to understand better, is within the upstream business specifically, why cash efficacy, so to speak, is deteriorating at higher oil.
If you can deliver a cash break even at $50 this year, this would imply free cash from the second half of around $14 billion compared to $11 billion in the first half. All else being equal, I don't want to put you on the spot, but are you comfortable you can deliver what is a 30% uplift in the second half? The second question on buyback. How should we think about the run rate per quarter in the context of the prevailing oil price? If oil falls below $70 in the next 12-18 months, I understand it's not a fair question, but can we still be guaranteed that $2 billion? Thank you.
Thanks, Christyan. Jessica?
Thanks. Thank you, Christyan. Good questions. I think in terms of looking at our cash and understanding break even, it is important to kind of cancel out working capital. That is a timing effect. That's a significant impact. I think you were quoting some of the CFFO with working capital. It does bring you down closer to the $60. I think what you'll see happening over the coming quarters is increased cash generation coming from the portfolio. We're still continuing to ramp up. We still expect dividends coming in stronger in the second half of the year, and the new projects coming on stream. All of that will contribute to higher cash generation and I think moving our break even price into the range where we'd like it to be.
I think on the share buyback program, I've spoken to it, I think I've tried to convey confidence in terms of the amount of cash we expect to be generating in the second half of the year, but importantly through the next two and a half years. It really is a multi-quarter, multi-year decision, and we're starting it with confidence. That's what the $2 billion represents. That's what the restatement of the $25 billion represents, is our belief that the underlying performance of the company is strong, that growth is strong, and, in combination, we'll have sufficient cash to deliver on this commitment. The working capital piece I think is important to kind of isolate. It is a timing effect. It's had an impact this year. It's had an impact in the last four quarters. Again, that will right itself through time.
Okay. Thanks, Jessica. Indeed, the curse of rising oil prices. Can we have the next question please, operator?
Yes. We'll go next to Tapan Polley with Exane BNP Paribas.
Yeah. Hi, good afternoon. It's Tapan here. I had a couple of questions, actually. Firstly, could you talk about how important the disposal program is now to the buybacks going forward? Does Shell need to be more aggressive than the sort of $5 billion I believe you've indicated per annum beyond 2018? The second question, I appreciate your comments around LNG Canada and fitting that in the terms of affordability. How do you prioritize debt reduction, buyback, and where you sit in the range for capital investment? Would you prefer to be at the lower end of the capital investment program, vis-a-vis meeting your buyback and debt commitments? Thank you.
Okay. Good questions, Tapan. Let me take the first one and have Jessica talk to affordability and capital discipline, and how that sort of ranks in the priority of use of cash after that. I think in terms of the disposals, of course, the disposals have played a very important role in delivering additional cash that we could use to pay down debt. I think so far we have done that quite successfully. We are essentially through the program that we announced at the time we did the BG deal. We talked about a $30 billion sort of portfolio high-grading program, which indeed had that benefit of delivering the cash, but from a strategic perspective, was as much also an upgrading program, a rejuvenation program of our portfolio. I think that is largely done.
The numbers that I quoted earlier, $27 billion done, three announced, four pretty close, means that of course we will deliver against that expectation. We will have to continue that program, Tapan. Of course, it will help if we get some cash from divestments. It will help strengthen the overall financial framework, or it will help with the buybacks or whatever way you want to look at it. We will be driven in terms of our divestment program by the need to keep the portfolio rejuvenated rather than free of cash. We think that we need to do about $5 billion a year to just do that. That's not a target for cash delivery.
That is the expectation we have if we want to have a strongly rejuvenated portfolio where we do not invest any more in assets or in markets that are very mature, and where we frankly are better off freeing up that capital employed and recycling it into younger and more vigorous positions. I do not think we are going to need the disposals for our financial framework, but are going to much more look at it as a sort of natural portfolio maintenance process. Now, how to prioritize cash, and particularly how new investment decisions fit in, can you take that question, Jessica?
Absolutely. We believe in order to deliver the world-class investment case, we need to grow the company, grow value of the company. We need to ensure a resilient financial framework, a robust balance sheet, and we need to increase shareholder distributions. We're going to manage all three of those things through the cycle and prove all of them to be true. We're going to invest some $25 billion-$30 billion. That's going to allow us to achieve our strategy, to achieve our ambitions for each of our strategic themes, and to grow value of the company. We're going to continue to deleverage over the coming years.
We're going to use the remaining proceeds from our disposal program going forward to continue to pay down debt, as we've done in the last year, and that will continue as we seek to achieve a gearing of no more than 20% over the next couple of years. Finally, to meet our commitment with respect to the BG acquisition, and importantly, to increase shareholder distributions. We believe all of those things are important, that we need to manage all of those things. We've been stepping through this process over the last couple of years and demonstrating unwavering commitment in terms of deleverage on the debt side, maintaining unwavering commitment to our dividends, removal of the scrip program, and we're now in the next phase of the world-class investment case, which is increasing shareholder distributions. All of it's important.
We believe we'll generate enough cash over the next couple of years for all of that to be true, to allow us to invest in projects like LNG Canada within the $25 billion-$30 billion program and grow value for the company through time.
Thanks, Jessica. Thanks, Tapan. Can I have the next question please, operator?
Yes. We'll go next to Alastair Syme with Citi.
Hello. Couple of questions from me. Your debt metrics are still, well, sorry, your debt rating rather is still 2-3 notches below the AA metrics you talk about. I wonder where you stand with conversations with the rating agencies as you now formalize this buyback, with a view to getting that debt upgraded. Secondly, the messages, Jessica, you made about the Permian growth, you're clearly big believers in the Permian. Can I ask your view on appetite to take on more acreage in the Permian if opportunities arose and where you think current market values are to enable you to do accretive deals?
Okay. Thanks, Alastair. Let me take the second question, Jessica can talk about our credit rating metrics. Yes, we look at our Permian position with satisfaction. I think it is not only sort of past the inflection point where we see a very fast pickup of growth, but also we expect this position to be a good cash generator in the near term. It will be a very important component in our overall Shell story where we expect to be cash positive in 2019, hopefully very quickly get into this business being a contributor to our overall dividend cover. Of course, we have made it very clear in the past we are interested in extending our position because I think relative to our other building blocks of our upstream portfolio, you could argue we are underweight in Shell.
We have a positive disposition to looking at bolt-on opportunities, and that's what we have been doing or growing in places like Argentina where there is an established system that works for us and where we can bring a difference in terms of skill. We've also been very clear that we do not want to participate in a gold rush and that we need to be also here extremely disciplined in how we approach it. Moreover, we've also been very clear that whatever we do, we won't go above $30 billion of capital investment in any given year. From that, you can derive how we are going to be looking at opportunities. We will look at them, but don't expect any big splashes. Jessica?
With respect to the credit metrics and the AA rating, I reference AA equivalent metrics a lot when describing our cash flow priorities, our financial framework priorities, that's remained unchanged for the last few years, and I think we've demonstrated that commitment. Why is that? I think it's important to note this reflects the view of the financial framework and the balance sheet that we think is most appropriate for our company. Given the size of the company, given the size of our capital profile, given the nature of the industry that we're in, we believe a robust balance sheet is an important piece of our financial framework, an important piece of our world-class investment case.
It just so happens that translates into a AA credit rating, the metrics associated with that, the amount of cash we should be generating relative to our debt, the amount of debt we have relative to our equity, we believe is important, and we're continuing to manage the company to move it to the place where we think it needs to be. It happens to correlate with a AA credit rating outcome. As I said before, by making this choice and then starting the buyback program and committing to the $25 billion, we're seeking to generate cash over the coming years that makes all of this true.
That we continue to have debt reductions in the company and generate sufficient cash such that we have AA equivalent credit outcomes in terms of our financial metrics, while also continuing to grow the company and do these buybacks. All three of those things we're looking to achieve over the next couple of years.
Okay. Thanks, Jessica. Operator, can I have the next question?
Yes. We'll go next to Biraj Borkhataria with Royal Bank of Canada.
Hi. Thanks for taking my question. It's Biraj, RBC. I have two, please. The first one was on integrated gas. Given a few successive quarters of these margin calls and headwinds, I was wondering if you could just give a bit more color on the key drivers behind that. Is that just structural as part of the LNG business, or I'm assuming it's a function of the oil price. So in a scenario where the oil price was to stay flat, would that go from a headwind to a neutral factor? Just some color on that would be helpful. The second question is on refining and trading and specifically focusing on the trading contribution. It looks like year-to-date it's been quite difficult. I was wondering if you could comment on how big a factor moving into backwardation is to the trading business. Thanks.
Okay. Thanks, Biraj. Can you have a first go at them, Jessica?
Okay. On the first question, in terms of the margin calls and headwinds, the margins do just represent the cash required, depending on where the curves are moving at any point in time. It's not really a signal of performance of the business. As you can see, IG has had very strong performance the last couple of quarters. A function of that has to do with our hedging program, and with the hedging program, a portion of that is subject to margin calls. I wouldn't overread into whatever the margin balance is at a moment in time. I would look at the underlying performance of the business and the strength of the cash generation that you continue to see in IG.
Indeed, all things being equal, if prices were not to change, you would see no change in the amount of cash margining that's required for the business. Again, that is an indication potentially of where the position is. In terms of what that position means and the value we're creating, you really need to look at the performance of the IG business to see that overall the trading business is making a material contribution, and a margin is a part of having that business in play. In terms of the second piece of your question on trading, indeed, trading has been a bit soft for us for the first half. It has been a difficult trading environment. On the product side, it's been a bit of a mixed bag, going from somewhat weak in the first quarter to stronger in the second quarter.
On the crude side, the business has not been as strong as we would've liked and is a focus for the business. We don't think there's any structural issues. Some of this just happens to be what happens in a given quarter. There's no fundamental concern. Clearly recognition, trading conditions have been a bit harder for us. We look to get more from the business in the coming quarters.
Okay. Thanks, Jessica. Thanks, Biraj. Operator, can we have the next question?
Yes. We'll go next to Christopher Kuplent with Bank of America.
Thank you very much. I've got two questions left. First one probably for Ben. Ben, I think amongst your peer group, the only ones without a top-line guidance for E&P. I just wanted to, once again, ask you, reiterating the buyback as a strategic element of cutting your annual dividend distributions. That's well understood, and that's one thing. Can you also perhaps give us a little more color about where you see the profile of the company evolve towards 2025, and how to care about a top-line measure versus an overall absolute cash flow generation engine that is the entire group? Then secondly, I know many have tried. I'm going to try again, perhaps Jessica, for you to come at it from a different angle. $2 billion of buyback in that quarter.
Am I correct in assuming that that $2 billion is funded from excess free cash flow left over after working capital changes or before? Is there no such definition we should even focus on? As I understand it this quarter, if you stripped out working capital, you would have been left with about $1.6 billion of free cash flow, even after deducting the $700 million or so of net interest payments. Is that the number that gives you confidence to now announce $2 billion for the next quarter, or am I reading too much into it? Thank you.
Thanks, Christopher. Let me have a go at your first question, tell me if I read your question perhaps incorrectly if that's the case. In terms of top line, of course, giving guidance on revenues, we don't do. For that, being in the commodity business, I think would be too meaningless to do. If you were referring to production and production growth, yeah. We have been abandoning that practice some time ago as we thought and saw it was sort of increasingly irrelevant. Actually in some cases, quite unhelpful because we felt that not only us, but perhaps others would be tempted to chase barrels for barrels' sake, which we believe is not the right way to manage a company.
Ultimately, we give and we have given guidance, of course, on the amount of cash we expect to produce, particularly free cash flow, which I think is a much more meaningful measure for you to go by. Of course, we reference that at a certain oil price outlook. Otherwise, that would be relatively meaningless as well. It's $25 billion-$30 billion of free cash flow at $60 Brent real terms 2016. We think that that actually is ultimately what it's all about. Can we deliver a very significant corporate transformation from going from a relatively modest free cash flow to a much higher free cash flow in a relatively short period of time? I think that is how I would like to be judged on our ability to deliver shareholder value.
With it, of course, also a significant improvement in returns so that you have an indication as to how disciplined and wise we have been in allocating capital. I have no inclination or intention to somehow go back to giving production forecasts. Again, because I think they are increasingly irrelevant in a business that is also, of course, very much driven by other emerging strategic themes like petrochemicals, like oil products, integrated gas, which doesn't always come with barrels associated with it. Over time, perhaps also power. I'm not sure whether that was what you were after, when you talked about a top-line measure, but this would be my response if you meant with it production growth.
Indeed. Yeah. Thank you very much, Ben.
Good. I'll pick up the question on the buybacks and what's driving our confidence. What's driving our confidence is the $11.6 billion of cash flow from operations, excluding working capital for the quarter. If you add back the margining, you get to $12.4 billion for the quarter. Importantly, it's not only confidence in today's performance, it's expectation and confidence in the second half cash flow generation. Importantly, as I mentioned before, really looking at this decision, our financial framework, our delivery of the world-class investment case over a multi-quarter, multi-year perspective. It's having confidence in the free cash flow growth that I've spoken to earlier today. I do think it's important to see through the working capital. That really is a timing effect. That shouldn't overly influence a decision at any moment in time.
It's really looking at the underlying cash flow generation of the business and our capacity on an organic free cash flow basis to support the share buyback program. Again, that's what our announcement today signals is confidence in today as well as the future.
Okay. Thanks very much, Jessica. Jennifer, do we have another question?
Yes. We'll go next to Lydia Rainforth with Barclays.
Thank you, and good afternoon. Two questions from me as well, please. In terms of the operating expenses, taking your point around the FX issues, are they developing as you would've expected at this point coming through? They just look a little bit higher given where the volume numbers have moved? The second one, I apologize to come back to the buyback as well. In the statement, it does say that it'll be subject to further progress with debt reduction and oil price conditions. Can you talk about how the pace of buybacks, or possibly just a different way to put this, if the oil price was $65 rather than $75, would you have actually taken the decision to start the buyback with this quarter? Thanks.
Okay. Thanks, Lydia. Let me, for a change, take away a buyback question from Jessica. I'm sure Jessica will have a few things to say about OpEx as well. No, I think, Lydia, let's go back in history a little bit when we came out with the statement that we would do a $25 billion buyback program at the time of the BG prospectus. We very clearly said subject to oil price recovery. Matter of fact, specifically, we mentioned getting back into our sort of traditional range of $70-$90. Of course, the business is dynamic. The macro has proven to be dynamic. Lots of things have moved. You can see that we are much more resilient probably even than we communicated and expected in those days.
I think an important conditionality remains, which is that if we see a very significant downturn again in oil price, of course, the pressure on the financial framework will change commensurate with that. We don't have mechanics in it's important to have a disclaimer in there that I'm sure you will understand. We cannot continue doing buybacks irrespective of where the oil price will go. Where we are at the moment, we are very confident that with where we believe oil prices go, or may stay, and what we believe our forward-looking operating performance, ramp-up of projects, et cetera, is going to be, we can execute that entire buyback program. That's why we have not only signaled the start of it, but again want to reiterate that our intent very clearly remains to do the $25 billion by no later than end of 2020.
Jessica?
Good. On the OpEx question in terms of expectations, maybe start with the larger frame. Of course, we've taken $10 billion of OpEx out over the last couple of years. I've been very pleased with the performance of the business and the way we've responded to the circumstance and are running the company much more efficiently and effectively than we had been in the past. We're going to continue to drive that in the organization. That being said, what you see in the numbers, there is an FX effect. That's a bit of a circumstance. It's not something we necessarily worry about. It's not helpful in terms of the optics. That's certainly playing into the view and the sentiment on OpEx. There's another piece of it, which is growth.
There is growth happening in the business, of course, in our marketing business, which Ben spoke about earlier. Growing in places like Mexico, India, China, et cetera. Those do bring in costs a bit ahead of when the margins start hitting the bottom line. Some of that's happening. Bringing in some of the New Energies businesses, that's also some of the growth that we're seeing. Of course, the transformation of our assets with respect to the divestment program, bringing the Motiva assets in, all of those have an impact on the OpEx, which isn't necessarily a problem, but it can be a reason for an increase. That all being said, there's parts of our OpEx performance that I'm not satisfied with, that I don't think the EC or Executive Committee is satisfied with as well.
We remain fully committed to driving the right costs in the organization, driving simpler ways of working, de-layering the organization. Those efforts are still continuing. Some of them are not necessarily moving at the pace that I would like. A lot of them are. What I would say is there is some soft spots here. We're not completely happy with our OpEx performance, but it remains a key priority for the group, and we're going to continue to drive simplification of our business where it makes sense and pursuing the right cost outcomes across the organization.
Thanks, Jessica. Let me also indeed, make sure you understand that it's not just the Executive Committee, it's also the CEO who wants to make sure that we keep completely on top of our cost performance, and do not tolerate any looseness in areas where we can be much tighter. Okay, Jennifer, can I have the next question, please?
Yes. We'll go next to Irene Himona with SG.
Thank you very much. Good afternoon. I had two questions, please. Firstly, integrated gas in Q2 had a $1 billion credit, a special credit. I wonder what that relates to. My second question on dividends received in Q2, we saw a 17% lower figure. Last year, dividends received accounted or contributed something like 14% of your group cash flow from operations. I think, Jessica, you did indicate you expect a step up in the second half this year, but I wasn't clear. My question is, can you clarify, can you guide whether you're looking to make more than the $5 billion in the full year 2018 that you made last year in terms of dividend received? Thank you.
Thanks for the question, Irene. Jessica, can you shine some light on that?
On the first question, Irene, I think we'll need to get back to you and so we'll pick that up with IR. That number's not obvious to me at this moment in time, so I just want to make sure that we understand the question and we get you the right answer. Indeed, on the dividend side, we're expecting dividends to come in stronger in the second half. That, of course, is always subject to partners, and other circumstances. Given the underlying performance of our various ventures and the expectations, we would expect in the second half that number to be higher than in the first.
Okay. Thank you. Jennifer, can I have the next question, please?
Yes. We'll go next to Lucas Herrmann with Deutsche Bank.
Thanks very much, Jess, Ben. Afternoon. Couple if I might. The first one, Ben, can you just put Silicon Ranch in context for me? Maybe this is a little abstract given where we are in transition and everything else, but just the thinking behind positioning in that asset. Secondly, I just wanted to come back to your comment on competitive with North American or with Gulf Coast LNG, in essence, where you understand netbacks to be or profitable netbacks to be or prices to be for Gulf Coast LNG, i.e., what the absolute MMBtu price that you think LNG Canada has to deliver if it's going to be competitive and economic?
Very good questions. Thanks, Lucas. Silicon Ranch is a solar project developer that we bought into with a minority share, but at the same time, gave us access to their IP and sort of trade secrets and capabilities that we could use also outside North America. What we see as part of our New Energies strategy going forward is that solar is going to be most probably the single largest growth component in the power system of the future. Having a capability to develop solar projects is going to be key.
We have looked at can we grow that capability organically, and we've come to the conclusion that perhaps we could, but it would just take too long, therefore, we have been looking around, which are the sort of relatively modest to small scale solar developers out there that have a very successful track record, that have a good funnel of projects to work on, and that ultimately we can integrate into Shell as an integral capability of developing solar projects around the world. We've screened quite a few companies. We've been in dialogue with quite a few companies, eventually we settled on Silicon Ranch because we thought it ticked most of the boxes. Where we are at the moment, indeed, we have completed that transaction. They came indeed with an interesting funnel of opportunities, predominantly in North America, actually exclusively North America.
We have seen them deliver on that funnel, actually grow that funnel. They're ahead of their own plan and the plan on which we valued that company. At the same time, we have been able to basically lift capability out of it through staff that we have seconded into it and use it for solar developments in other parts of the world where we know we will have to grow our position going forward. Opportunities that we are looking at in the Netherlands, in Australia, but also opportunities we may have in places like India, et cetera, are all on the back of the capability that we have picked up with Silicon Ranch. It is not just an investment that brings value here and now. It's also very much acquiring a strategic capability.
Gulf Coast LNG, we see, of course, the share of Gulf Coast LNG grow in the overall energy business, or markets, I should say, to about 20%. Increasingly, Gulf Coast energy will be an element in the price setting mechanism. Therefore, if we were to consider the economics of LNG Canada, it would be prudent, as it is also, of course, in a way Henry Hub correlated, although not entirely tightly, to see how that would compare with a Gulf Coast supply project. We need to make sure that as we consider a final investment decision on LNG Canada, that it is competitive against Gulf Coast LNG on the landed cost. Ultimately, without that competitiveness, both in terms of financial competitiveness as well as for the longer-term carbon competitiveness, this project would not be suitably advantaged.
We want to invest in projects that are structurally and fundamentally advantaged, but also structurally and fundamentally resilient. As Jessica said, come what may, or what you could reasonably expect to be the price environment in AECO and the price environment in, say, Tokyo Bay, this project needs to deliver a consistently strong positive free cash flow for decades to come. These are some of the considerations we are currently looking at. We believe, indeed, the project, because of its access to very large quantities of low-cost gas, its proximity to market, and its very high-quality design that we have produced, has indeed the potential to be competitive, resilient, and it is indeed going to be affordable if we decide to go ahead with it.
Ben, where do you see landed cost?
Can we have the next question, please, Jennifer?
We'll go next to Jason Gammel with Jefferies.
Thanks very much. Since the Permian Basin has graduated to having a slide in your overall deck, just wanted to ask a couple questions on strategy there. First of all, I'd like to understand what Shell intends to do from an operator perspective, because if my understanding is correctly, your JV partner has been operating about two X the number of rigs that you have been in the basin, and I believe operates about 70% of the acreage. How much of your growth targets are based upon your ramp-up in operated activity, and how much is based upon your understanding of your partner's intended activity levels? Second to that, clearly takeaway capacity is a potential restraining factor on production growth in the Permian Basin, at least in the near term.
Can you talk about what you've done to secure firm transportation capacity out of the basin for these growing volumes, and also ancillaries that what you've done in terms of natural gas processing?
Okay, very good question, Jason. Indeed, Permian has a growing prominence in our way forward. Let me have a first stab at answering the questions. I know Jessica has been looking at it in considerable detail as well for a number of reasons. First of all, we believe we have a very strong track record of delivering competitive drilling and completion cost. It's relatively easy to benchmark it, and I believe that we are ahead of industry in the Permian, and you can draw your conclusions what that actually means for some of our competitors. We, at the moment, are pretty much at a 50/50 position in terms of rigs. That is not important as such. I think we will make our decisions on the basis what we believe makes sense for us in terms of growth.
Of course, there is a little bit of tactics in there where we want to make sure that we have the ability to dedicate certain developments to certain infrastructure. That's not necessarily driving the investment pace that we have. The investment pace predominantly is driven by our ability to generate free cash flow and the returns that such an investment would have. Takeaway capacity. Indeed, it's an issue in the industry. We have been looking at a more integrated picture for our upstream piece, midstream piece, and trading ever since I know. Jessica is very familiar with that, and I'm sure she can comment on it in much more detail.
We take a holistic view, not so much how much can we produce on the pad, but also how do we get it to market, and how do we make sure that the integrated value is truly optimized. That means that we have taken some positions, perhaps, Jessica, you can explain that in a bit more detail.
Good. Just picking up on the takeaway capacity piece of your question. Indeed, this has been on our mind for years. I happened to be in the unconventionals business in 2013, 2014, and we were looking at the growth in our portfolio and the growth in the industry and anticipated to some extent what we're seeing today. Back then we secured firm commitments across pipelines to ensure we had flow assurance for our growth, which we're experiencing today. I think that speaks a bit to the strength of our trading business and the strength of integration, and working across the organization to manage these risks effectively, and doing so today. I think on the first piece, on the operator perspective, just a couple points to add there. We, of course, look to drive value through our partners, whoever's operating.
In all of our NOVs, we continue to actively engage and bring insight and support where it's needed to drive value. It's rarely kind of passive engagement. We've got a good relationship with Anadarko. We're continuing to drive value for both of the companies. I think we're frankly getting better at that. We're continuing to see a lot of innovation within our own business, looking at developing multiple horizons with our wells versus kind of one horizon at a time. I think it's part of a next generation of improvements we'll be seeing coming out of the Permian and why people, I think, continue to see a lot of upside with the Permian acreage. As I also mentioned, we're doing swaps. Again, we're continuing to maximize or optimize our portfolio, which also has operator implications as well.
I think there's a number of levers we're pulling, whether it be how we manage our midstream exposure, how we work with Anadarko, or how we continue to kind of expand our position, even if modestly, but wisely with the swaps and pushing the next generation of technology and innovation with respect to our shales business .
Okay, thanks very much, Jessica. Jennifer, can we have the last question, please?
Yes. We'll go next to Gordon Gray with HSBC.
Thanks. It's another question on cash flow, I'm afraid, but at least it's a quick one. All I wanted to ask is you've had these big headwinds in the recent quarters from these tax settlements. Can you just confirm that apart from what you mentioned on Oman, the 2Q numbers are effectively clean of any other tax issues, tax settlements? I guess more importantly, are there any others in the pipeline? Which I'm sure you can't give us details on, but that you're talking about that could come through and affect cash flows in the next few quarters. Thanks.
Thanks, Gordon. Very clear question. Jessica, would you like to take it?
Yeah, I think that's entirely in my realm.
Yes.
Thank you for the question. Indeed, a lot happens in our portfolio from a tax perspective, both in earnings and in cash. From a cash perspective, what you've identified, what we mentioned in the call today, the Oman payment was the most material. There was nothing else kind of unusual happening from cash tax payments for the quarter. They've increased as the mix of our business has changed. We are seeing more profits in upstream and IG, there's a natural impact on cash tax payments, which we're seeing, which I think is relatively straightforward. We also provided some guidance in terms of what to expect of further tax changes associated with the item that came through in Q2, trying to help provide a bit more transparency in that space.
It is dynamic and something we talk about in terms of how to provide the right level, the appropriate level of transparency. It is a dynamic portfolio, and also as I said, with the divestment program that can have particular impacts on both earnings and cash taxes that we'll continue to see, I think, to some extent for the coming quarters. It's difficult for us to provide that until those transactions actually take place. We're trying to provide more transparency as appropriate. Other than ones that I identified already, I don't think there's anything really for us to signal at this point in time.
Okay. Understood.
Thanks very much, Gordon. Thanks very much, Jessica. Thank you very much all for staying with us until the full length of the call scheduled was completed. Thanks for great questions. For me, rest to say that the third quarter results are scheduled to be announced on the 1st of November. Jessica will talk to you then. Thank you very much, and enjoy the summer.
This does conclude today's conference. We thank you for your participation.
