This is a good opportunity for us to show you some of the talent we have within the company. Matthew was our first employee into our Kuala Lumpur office. He's a very highly skilled geologist and he's responsible for a lot of the work that's going on on our operator block Topaz as well as a lot of the work we did on Block 2A. He and Dr. Pierre are very well placed to tell you all about that. What we want to do today, I'll give a little bit of a scene setter, then I'm going to hand the bulk of this to Dr.
Pierre and Matthew to talk to you about Malaysia in general in terms of its geology, zooming down on some of the key basins, the Sarawak area, and then over to the Malay Basin in the west and talk about the assets we have operated, Block 2A and Topaz in particular. We'll also give a little bit of a heads up on the Dewa block and what's going on there. We'll cover the entirety of our portfolio. First of all, Malaysia. We say here it's the right time and the right place. As we show on this slide, the majors, the larger companies, clearly agree with us. It's always been the home for Shell and ExxonMobil, but recently we've seen TotalEnergies and Eni take big positions here.
This is a province with some very, very large companies roaming around in it, which gives rise to a big strategic question for companies like us. How do you thrive and compete in an environment where you have these very large, these large beasts roaming around which we are going to struggle to match their firepower? I want to come back to that in a moment. Clearly, Malaysia has prolific basins, which is what's attracting these companies. It's got a very understanding NOC and regulator, which is fantastic. One of the big advantages we see in Malaysia is the data access. We have access to prolific amounts of data, which is a huge benefit when you're a small, technically led E&P company like we are. To get that is really meat and drink for us.
In terms of right time, the demand story, which we're not really going to talk about here in terms of gas at least, is very, very strong right now. You know, you'll see a gas shortage in Sarawak crying out for gas to go to Bintulu LNG and over in Peninsular Malaysia for power generation, they need more and more gas and right now they're having to import LNG from Australia into Peninsular Malaysia, which is one of the big drivers as to why they want more exploration and more gas on stream very, very quickly. You have an extremely supportive macro backdrop for companies like us to operate in. I think coming back to this strategic question about how we can compete, one of the great advantages we have is that we're not a big giant. We can act very quickly, we can be very agile.
We're not a prisoner to five-year corporate plan timetables or even, frankly, annual budgeting cycles. If we see something we like, we can go and act on it. We can drop everything and direct our resources to go and capture that opportunity. We also have a very good dialogue with the NOC. We're not reliant on big set piece conferences or visits from head office to come and talk to the regulator. We have an ongoing dialogue with them the whole time. We're in and out of their office all the time. Any ideas we have, anything we see, we can talk to them about straight away. We don't even have to wait for license rounds actually to raise this sort of thing, so we can be truly opportunistic.
That's something that I think the larger companies struggle with, particularly in an environment like this where you have super majors, you have other national oil companies, you have very big international gas companies, but you have very few small companies like us. That brings me on to this next point, which is the opportunity set in front of us. This is Wood Mackenzie's slide. This is a leading industry consultant. It's not our view, but I would totally agree with them that there are many, many hundred sub-commercial discoveries sitting around in Malaysia, both in the west and the east. Most of those are sub-commercial for very good reason. They'll probably never see the light of day. They are probably marginal in terms of the economics, but some of them will be extremely valuable and they'll be much bigger than people think they are.
Our role in life is to seek these things out and try and make them work. Here we are. From what we see, oil is quite difficult. If you have a very small oil field and it doesn't get developed according to plan, something doesn't quite work, it'll kill the project. With gas, these tend to be volumetrically much bigger, and so you've got more margin there to work with. The gas opportunities tend to look a bit more attractive to us, but you know, we're not wedded to it particularly. It does fit the macro narrative very, very well. We have a very clear role in life in terms of plucking these out. As I said earlier, there's very few little companies around, so we have very few competitors right now. The timing point is extremely fortuitous.
Just before I go, I'm going to hand over to Pierre in one minute. Here's our portfolio today, and before we get into it in detail, technical details. Block 2A was our flagship. We now have 10% of it. Really, we came by that asset many years ago because we saw a huge structure sitting out in the North Luconia. I wouldn't say that other people didn't know it was there. I think a lot of companies were aware there was a big structure there, but for whatever reason it didn't get chased until it came up in a license round. Even then, attention was taken away from it and people were looking elsewhere. For whatever reason, a big dose of perseverance and a lot of luck, we were able to catch it.
The work we've done since and what you'll see the guys talk about today, you know, we can now put the high quality reservoirs into that structure. We can see the gas charge. The story looks extremely attractive and of course the INPEX farm out is extremely good evidence of that. I think with Dewa, this is again us spotting an opportunity right in the heart of the Balingian province. We saw some undeveloped gas sitting close to infrastructure, close to the LNG plant, that no one seemed to be doing anything with. We were able to capture that as well. The whole thing really comes together with Topaz , where we were aware of the Tembakau discovery. Today you're going to hear a lot of Malaysian names. They're quite confusing, I apologize. Tembakau is the Malay word for tobacco. It's not terribly PC, but it might help you remember it.
The Tembakau discovery had some stratigraphic elements to it, we believe. Our idea was if you took those and looked elsewhere around it for other stratigraphic traps, you could unlock a whole new wave of discoveries of gas very close again to pipeline systems and infrastructure where it's really needed. The upside potential we thought could be really interesting. I think today is the first time we're going to show you some of that work. These two guys are best placed to do that. I am now going to pass this over to Dr. Pierre, who, what he doesn't know about Malaysian geology, you can forget, but he's going to take you through it.
James, thank you very much and hello all. I must say it's great to be here today and to be here with Matthew. We're both based in Kuala Lumpur, so it's great to be here today to walk you through this deep dive. What we have now is just a collection of slides running through the Malaysian basins and then to give a bit of a context of our portfolio and then we're going to go through the assets in some detail and , Dewa, and 2A and talk you through all that. We just thought we'd start with a few context slides. This slide is of the Malaysian basins, the Malay Basin to the left and the Sarawak Basin to the right. Our portfolio is right in the core and the heartland of these basins.
Topaz , of course, in the Malay Basin and 2A and Dewa in the Sarawak Basin. You know, when you just pause and look at this slide, it's quite remarkable. The slide here says over 4,000 meters, 4 kilometers of sediment in those basins. Actually, in the Sarawak Basin, it's probably amply more than that, but it just goes to show the amount of sediment there is in these basins that's cooking and generating oil and gas, which is then trapped in the fields that we are chasing in both Topaz and 2A. James alluded to this, but it's really remarkable the amount of data there is in Malaysia for us to work on. This is a database slide of the three main basins, the Malay Basin, Sarawak Basin, and Sabah up in the north there.
It's the access to the seismic, the 2D, the 3D, the wells, hundreds and hundreds of wells, the tests, the production data. What's remarkable is that all this is in an online database called myPROdata database, which PETRONAS have put together, which we have access to. We have access to all the data on our blocks, but also on all the blocks across all of Malaysia. We have a really extensive data set which is really remarkable. If we want to look at competitive activity or a block next door, we can look at the data there and form a view about the regional plays. Really extensive data set in Malaysia which helps us understand and de-risk the prospects and the plays that we are chasing. Really, really important.
I think this is probably one of the best databases and it's all online in the cloud worldwide, I think, that we have seen. We have a few slides on yet to find and this is how geologists measure the potential of basins and how the different phases of exploration in different basins. The slide on the left, Malay Basin, slide on the right, Sarawak Basin, and you can see there are periods of extensive activity where the graph shoots up. You can see this is in the 1970s in the Malay Basin, in the 1970s in the Sarawak Basin. There are pulses of success in exploration. If you look in Sarawak, there were key pulses, pulses where the graph goes up, and then recently with recent discoveries Lang Lebah and also the new field discoveries in Sarawak as well. What's interesting is the yet to find.
How much do the geologists of the geology community think there is yet to find in these basins? In the Malay Basin, the estimate is probably in the order of 3 billion barrels as yet to find resource oil and gas. Yet to find in Sarawak, because of course, remember on that first slide it's a bigger basin, so there's over 11 billion barrels of yet to find. These numbers of course are plus or minus, but gives you a sands of the potential. James said right place, right time, and I'd add right address. This is. These are the right basins to be in, and our portfolio is right in the heartland of these basins. That was a quick run through the geology of Malaysia.
I know it's super simple, but hopefully gives some sense of why we're so excited about our portfolio in Malaysia and the opportunity set it presents. We just have a few slides now to go through Topaz , and I'll just talk through two and then pass on to Matthew. Topaz of course is our flagship asset that we signed in June. Very excited by that. The round is part of the 2025 licensing round that was announced in January. Again, the pace and the rapidity that PETRONAS are working towards issuing these licenses and moving forward with these programs is really exciting that we can move from bid in March to sign a new PSC in June to evaluating today. Really exciting and how fast paced activity is in Malaysia. Just two slides from me, just a reminder of Topaz .
Topaz on the map on the right is the blue box with Tembakau, the field that James mentioned in the bottom right. These were discovered by Lundin, which is now IPC, in 2012 and appraised in 2014. The audit we did in the summer in August with Sproule that we published, if you remember, had Tembakau at about 246, just shy of 250 BCF. Mengk uang, the small field to the north, about 30 BCF. This is 2C contingent resource. It's been audited by the audit firm, confirming those resources. They've looked at all the data, looked at all the wells. These are stacked Miocene channel sands and they are clearly identifiable on seismic. The water is very shallow, so the development costs are low.
All this gas, when it's developed, will go to nearby infrastructure and then back to pipe, the big pipe that you see on the map there on the right, going back to landfall at Bintulu where PETRONAS will buy the gas. I think one thing that is remarkable about this asset is that the size of the PSC that we have, the PSC is 1,200 square kilometers. We no longer not only have to develop Tembakau, but also appraise and explore the large area of 1,200 square kilometers, which is the extension of the Tembakau play across that block that James alluded to. I think we touched on this earlier, but significant demand in Peninsula Malaysia for gas coming from these fields.
There's huge demand and I think the whole demand picture has changed considerably where there's a shortfall of pipe gas coming from these fields offshore east coast and there are these long-term import contracts from Woodside and others importing LNG into Peninsula Malaysia to support demand. It certainly is right place, right time on this asset. Just as I introduced to Matthew, we believe there's huge potential in this area. Tembakau itself, just shy of 250 BCF. These channels we see at Tembakau extend to the west and northwest in a feature that we call Keladi and then into a large feature that we call Alamanda, those two yellow blobs. These are targets of slightly different geological horizons, but we've put them on a map in the center there for simplicity, all in one place.
The beauty and the message I get from this is that if Tembakau is 250 BCF, let's say Keladi could easily be 200 BCF and Alamanda is easily 400 BCF or so. In fact, the upside number from the auditors had Alamanda up to 700 BCF that we'll show you later. Do we have the potential to create up to a 1 TCF gas hub in this area? This would be really revolutionary and change our view of the whole area, which is for all of us really exciting. That's enough for me. Matthew,
Dr. Pierre, thank you very much.
Great.
Thanks for the introduction. James and Dr. Pierre both alluded to the fact that one of the key reasons why we're successful here is the richness in the data set that we have. What you see now on the slide here in the center figure is the availability of the data that we have. Everything in purple is the extent of the 3D data set that we have in the block. You can see immediately where the Topaz block is sitting right dead center. By and large, the entire block has been covered by 3D. We have also other data like the non-seismic data, which is the figure on the left, which is the FTG data, which is the full tensor gravity data that PETRONAS has shot over the area.
This helps us a lot because it helps to delineate the basin, helps us to identify where the structural elements are, and helps us also to understand the basin a little bit more in terms of where the charge could be coming from, how the charge migration is migrating from the center of the Malay Basin to the north into the area where we are right now at Topaz . One of the key things about Topaz is really about how easy it is to target our reservoirs. Our reservoirs are in three reservoirs. It's the I10, I20, and I80. I'll talk a little bit more about them later on the next few slides.
The key thing here is through this, what we call seismic amplitudes, we can actually identify these features, what we call channel features, fluvial systems, tidal bars, which you can identify and actually use analogs of present-day features to help us to understand what those reservoirs could be like. Those are important because understanding those reservoirs, or what we call facies, helps us to delineate or understand the producibility of these reservoirs and also helps us to figure out where else can we find additional perspective from this facies itself. Within our block there are different models sitting out there. Where we are right on Topaz , we are looking at the fluvial system. In the deeper I10 reservoirs associated to those systems, we have tidal flats, we have crevasse splay, we have point bars.
As we progress forward to the younger reservoirs in the I10, we get into the more tidal environments. As you can see on the figure on the right, you can just imagine going on a walk on the beach and a long walk from the river down to where the beach is. You can see how the river system changes from what could be a very restrictive river as it spreads out as you go towards the coast. It spreads out and you get into more of your tides environment and sometimes even to the shorelines. You get some of the waves. We don't have any of the waves here, but we got a lot of tidal influence influencing our facies and influencing how our reservoirs have been deposited.
That's important because they help us to plan our wells, help us to find where the additional prospectives are within our block. What you see on the left here right now is what we call a seismic section. This is what we do when we go out there. We shoot seismic. We put cables, we tow cables behind seismic ships, which sends a signal down into the subsurface. We record the bouncing of the signal up with receivers. We have processors that process this signal, which give us the image on the left. Now what's important here, you can see immediately the difference in the colors of the seismic section here. The colors are important because it differentiates what we call sands, just kind of sand with water in it, and also differentiates what the gas bearing sands are.
Due to the difference in the elastic properties of water bearing sands and gas bearing sands, you will get an impedance and the impedance shows up with bright colors. As you can see on the side section there. What you see also in the side section are the logs which we acquire when INPEX Corporation drilled the Tembakau 1 and Tembakau 2 wells. You can see immediately where you see the inflection of the red bars on the well is where the gas pays are. Immediately on a section you can see vertically, there are different pay zones. You got the I10 sands, got I20 sands. We also have the I80 sands. We received some shows. We saw some shows in the I35 sands, but just shows, it's not enough to be commercial. The main sands we're going after are I10, I20, and I80.
There's a section on the right we can see. It's a schematic cartoon of the different reservoirs and how they are stacked together vertically. That's important because it helps us to maximize the value of a development by having stacked reservoirs in this Tembakau field itself. Just zooming in on the well logs, we have Tembakau 1 on the left, we got Tembakau 2 on the right. What's important to note is that in each of these wells we saw excellent reservoirs. We did evaluation on it. The I10, I20, I80, we have high porosities of the range of 35% porosities, multi-darcy permeability, which is important for us because what that means is that we get great flow rates when we eventually develop from these reservoirs. We did tests on some of these reservoirs, particularly in the I10 and I20, what we call the DST as drill stem tests.
What that indicates is how good the flow rate potential could be coming up from these reservoirs. Those tests have indicated that we could flow up to 50, up to 60 million scf per day from the I10 and I20 reservoirs. Also important is of course the quality of the gas we see in these reservoirs. We took samples when we drilled these wells and the analysis of the samples indicated that we have sweet gas. What that means is that we have no CO2, we have no H2S, we have very low nitrogen, we have sweet gas so much so that it can almost flow into the kitchen and start cooking. I alluded to the fact about amplitudes, right? We can see amplitudes because of the impedance contrast between gas bearing sands and water bearing sands. That's great for us because you can see immediately what that looks like.
On the map, right?
On the left figure you can see is the MP2 maps of the I10. In the center figure is the MP2 map of the I20. On the right is the empty figure. On the I80 you have the inset pie charts which indicates the volume contributions from each of these reservoirs to the entire Tombaca field, which is up to 200 close to 250 BCF resources. You can see immediately the brights on each of these maps. That's useful for us to develop this field because the brights tells us where the grade quality sands are, where the gas bearing sands are. It helps us to maximize our development plans for these fields. I'd like to bring your attention to the figure on the right. What's interesting on the figure on the right is that you can see the location of the two Tombaca wells.
You can see the Tombaca 1 well sitting right in the middle of the figure. Also just south of that you can see the Temakau 2 well. You can see where the Tombaca well has penetrated its bright amplitudes. That corresponds to what we've observed in the well logs. That is great reservoirs with gas in it. The Tembakau 2, when it was due, it did not see any gas in this particular reservoir in I80. We know that because of the amplitude maps you see on the figure. You will also see how that channel in that figure actually kind of translates and kind of moves up towards the north and further into the northwest. That's great news for us because that indicates that there could be more prospective gas bearing sands up north of us and also northwest of us. This brings me to this map.
You can see where the location of the Tembakau field is. You can see where the Keladi Prospect is alluded by Dr. Pierre. That was basically delineated by the MP2 maps we see in the previous slide. Also in the slide in the center figure here, you can see how translate itself up north of Tombaca towards the west, which forms the Keladi structure prospect. We also see this composite. This is what you see here. In the center figure is a composite MP2 map which is basically the stack response of all these MP2 maps together. The huge blob right to the left of the center figure there is what we call the Alamanda Prospect. Our Alamanda looks like is actually what you see on the schematic on the right. It's actually on a shallower stratigraphic level. Shallower than the I10 sense is different, but shallower.
It's never really been penetrated or evaluated in this part of the Malay Basin before. We think based on amplitude, we think that this could be really prospective for us. In terms of volumes, you're looking up to around 400 BCF of prospective volumes for the Alamanda Prospect. Huge values if that comes in. We talked about Keladi and this is just a science fit session over what we think the Keladi Prospect looks like. I alluded to the fact that Keladi Prospect was defined by seismic amplitudes. This is what it looks like on the actual seismic itself. The two wells you see on the right of the figure are the Tembaka 1 well and Tembaka 2 wells highlighted in red just at the Tempacan 1 well. It's the I80 sense.
You can see how the phase responds, the thickness of that loop, the shape of that loop, how you can actually almost correlate that loop across the fold in the center of the figure to the left. You can see how similar that seismic loop response is at Keladi Prospect. ERCE has evaluated the Keladi Prospect to have up to around 188 BCF with the chance of success of about 45% for this prospect. I've talked about Alamanda and this is the energy we have for Alamanda. Looking at the amplitudes of Alamanda Prospect itself on the right, you can see the extent of this amplitude, it's up to around 66 square kilometers in size. What's great about the prospect is its proximity to the Tembaka field.
It's roughly around 10 km away to the northwest, which is great for us because in the event of a discovery you can easily tie the discovery into the Tembaka overall field development plan. The figure in the center here is a figure taken from Google Map of a delta system in Myanmar. This is the analog that we are trying to use to describe what Alamanda looks like. It's a high stand delta which has been incised by subsequent sea level low which forms the traps to the north, to the west, and to the east of the prospect itself. This section here you see A to B is actually a northwest to southeast section across the heart of these Alamanda amplitudes. You can see where the high stand delta is, where this bright amplitude response is.
You can see the incision of the channels just to the left of dark bright and also to the right of these brights which forms the trap of the Alamanda prospects. Again, around 400 BCF of potential resource sitting in this prospect. Great location. Great, great potential development for the Topaz Cluster PSC. I just want to round up the whole Topaz kind of block for us. These are all the volumes that Sproule ERCE has invalidated for us of all the potential prospects we have in the Topaz block. You can see where those different prospects are on the map. On the right, the Alamanda prospect, you've got Keladi as well, just sitting north and northwest of the Tembakao field.
We also have this small Tembakao West near-field exploration prospective volumes just sitting to the west of that Tembakao fault, and also with the Kang kong prospect just sitting to the east of Tembakao field. Great, great prospects. If you add all those numbers up, who knows, potentially up to 1 TCF of potential resources available to be discovered. It's a great asset, isn't it Dr. Pierre?
It's great, Matthew. Matthew, thanks so much for that. It's really, really good. You know, when I reflect, Matthew, on the asset, you know we bid on this for Tembakau . Actually, what we have now is this huge portfolio of prospects, yes, in different places to the west and northwest of the block. It's really great and it's come on so much from when we bid in March and signed in June. All the work that you primarily have done over the past few months delineating all this upside. We had a very good workshop yesterday as well in London, just running through all the productivity on the block, and there's just more prospectivity emerging, which is great to see as we tease out the different plays from our understanding from the three wells on the block.
Dr. Pierre, you know you just mentioned the fact. I just want to draw on also the point that James mentioned earlier. It's just four months since signing and we have this. We have now identified so much more potential within the Topaz Cluster PSC. I think it's only possible because we are so agile.
Right.
No, it's great. It's a good story. It's a good story. It's a good story. We've wrapped up on Topaz here. I just wanted to walk through a little bit. We'll go further east now to Dewa PSC in East Malaysia in Sarawak. This is our non-operated asset that's operated by EnQuest in partnership with PETROS that we signed actually just about a year ago or just under a year ago next week. I think it'll be a year to the signing of this PSC. I must say EnQuest have done a huge amount of work on the block and delineated extensive, all the, mapped out and done the resource assessments on all the reservoirs across these different fields. This is a very interesting asset. It's a collection of 12 or so discoveries that were made quite some time ago in the late 1980s and the mid-2000s.
They're a collection of small fields that were really overlooked. As James said, the explorers who were looking at this back in the day were looking for oil pay and oil pay in deeper reservoirs and the reservoirs that they found were actually quite tight for oil. It was quite difficult to get the oil out. As they went to explore for the oil they went through significant gas sands and the gas sands they ignored at the time because gas at that time wasn't commercial. These reservoirs are really quite impressive and I'll show you some examples of these in a minute. This is shallow water gas fields that go back to infrastructure and then back to Bintulu LNG. It's a really good story. Bintulu LNG is looking for more feed gas in the years ahead as it continues production.
Of course all these LNG cargoes go up to North Asia, Japan, Korea, and China. I think what we said at the summer was that the ERC Sproule CPR that we did in August had this at about 330 BCF of resource 2C contingent resource. From the work I've seen, this is maturing very well and I think the fields are better than what I saw initially when we put the bid in in early 2024. The fields are just improving with all the work there is on them. I think we see plateau of about 100 million standard cubic feet per day going into the grid and possibly more. I think it's testament to all the work that EnQuest have done on this project. We have just a very simple line which I'd like to show.
This is a north-south line across the Dewa fields, north to the right and south to the left. What I like to say about this is just really simple structures but great reservoirs. We have these reservoirs trapped in these anticlinal structures 1, 2, 3 and forming really simple structures. It's really because the reservoirs are so good that we really think this asset is really interesting and good. This is the type well that we showed at the time when we bid on this. I think it's a really great example because it shows the quality of the rock. These are really high quality Darcy quality reservoirs but also the amount of pay. The yellow on the logs here is sand and you can see the amount of sand there is productive zones. What I like here also is that one of the columns is 97 meters.
So 97 meters of continuous gas column in accessing these high quality gas reservoirs, you know, 97 meters is huge. It's like a third of the height of the Eiffel Tower. It's very significant. To have these overlooked in this well known basin is really great to have as part of our portfolio. EnQuest doing a lot of work on this and of course are the operator and doing great work and progressing this very well. This is just some impressions from us on the quality of the asset. With that I just want to walk through 2A, a little bit, a few slides from me and then Matthew will talk you through the rest. I think a lot of you will know this story before but we'll just recap this a little bit. Of course we're staying in Sarawak.
I think we alluded to the landscape in Sarawak and I think the map on the right shows how the company landscape has really changed over recent years. Offshore Sarawak in the past of course dominated by PETRONAS and by Shell, very much Shell country. I think recently PTT and others coming in to Sarawak and making important discoveries. Also now TotalEnergies, very important position. You can see our 2A block and TotalEnergies coming in with acreage to the north, to the south, south and to the southwest of us, as well as to the east, and also TotalEnergies taking a controlling position in Sabah. I think there's an awful lot of attention in Sarawak and the companies that are coming in is testament to that. We have the map of Kertang in the middle there, which shows the size of the structure.
It's about 220 square kilometers of closure, of maximum closure. We put that sitting well inside the M25. I think you've seen that before as a slide. Of course, what's changed through the course of this year has been the operatorship with the operator, now INPEX Corporation in partnership with PETRONAS and PETROS and ourselves with the carried 10%. I think a really great position on this block and on this prospect. We just have a few slides to show you through this. I think from all the work that Matthew and I do in Malaysia, we see it as very much the largest undrilled structure in Malaysia. I've not really seen a larger one. It's really exceptional that it's not been drilled before. I'm certainly very passionate about seeing it drilled in due course.
We put this slide in because Matthew and I have been doing a lot of work, of course, with INPEX Corporation , the operator, and they've been thinking about this very carefully about where to drill this structure. The structure itself is, as we said, about over 200 square kilometers of closure. It's got several multiple objectives. It's got the shallow gas sands and it's got the cycle two and cycle one sands, all of which are slightly different and are better in different places. Finding the well and drilling it in the right place is really critical. It needs a lot of thought. It's great to see INPEX Corporation and PETRONAS and the whole partnership working on optimizing, getting the best possible well location for us to drill on this structure. We also put this slide in because I really like this slide.
It just shows how it's a culmination point in the sub region. All those bright to the left of the slide there are these coals that are feeding gas from this maturity kitchen up into the structure and some of the gas escaping in that gas cloud, as you've seen. We think this could be very extensive structure and with a very significant gas column. We're doing a lot of work with INPEX Corporation on the positioning of the well. Let me pass to Matthew now and talk you through a little bit more detail on the structure from his perspective.
Thank you very much. I'm also equally passionate about Kertang. We talked about Kertang being potentially one of the largest undrilled structures in Sarawak. There are actually a lot of other similarly equally huge structures that have been drilled in Sarawak over the past few years. You can see on the slide here three of them. For example, the bottom is Kasawari, which holds up to 6 TCF of resource. You've got Lang Lebah, which was drilled by PETRONAS, 5 TCF resource, and Marjoram, which is about 2 TCF of resource drilled by Shell. What you can see immediately just looking at this picture, you get Kertang on the left. You can see similarities in the structure. Obviously, the scale is different. Kertang is a lot larger. What you can see is similarity in the shape of the structure, which is like Kasawari, like Lang Lebah, like Marjoram.
What's important actually is what's above. What's sitting above this structure, particularly at the Marjoram field, you can see just the bottom right. Just sitting above this field is this chaotic kind of signature in the seismic, slightly bright, but also slightly fuzzy. You can see similar observations just sitting above the Kertang structure itself. That's a good thing because that actually indicates the presence of gas, a working petroleum system underneath Kertang in our block in 2A. That is one of the key things that we look for as geologists, as explorers, to seek out where these potential sweet spots are, where the combination of all the migration of gas and hydrocarbons could be ending up at. The fact that Kertang is such a huge structure, you can see the apex of the structure itself.
It gives us a great feeling of certainty that there's definitely migration of hydrocarbons into this structure. Again, going back to Kasawari, Lang Lebah, and Marjoram. Huge structures. These are high relief structures. Kertang we talked about, we talked about in Paris, the Paris Eiffel Tower as comparison, Kertang is in fact a lot, a lot bigger than that. In Malaysia, which is where both Dr. Pierre and myself are based, we always go to the PETRONAS Twin Towers. That's about 455 meters in height. Kertang is about double that, easily double that height. Really big structures. That's why we see huge potential volumes sitting in the Kertang structure of up to 9 TCF in resources as audited.
The column could be 900 meters. At Kertang
it could be up to.
900, double the height.
You have to stack two PETRONAS.
Towers on top of each two PETRONAS Twin Towers.
It gives you a sense of the scale, doesn't it?
It's amazing.
Yeah.
Wow. Just zooming in on Marjoram so you can get a bit better idea of what I was talking about. This is from a paper published recently in 2022. All right, you can see the structure on the bottom map inset on the right. How that looks like. Red is high, white is high, and the green is low. You can see actually what it looks like on at least can picture what it looks like in the aerial sense. The seismic section will tell you what it looks like actually on the seismic. You can see where those fuzzy zones are sitting on top of the structures. Slightly bright, slightly fuzzy. We call this gas clouds rightfully because those show us potentially where the gas are in the basin. Right.
Again, this is marjoram and we use this as analog for the Sarawak basins that there are still structures large enough undrilled in Sarawak that could contain huge amount of potential resources. You know, we talked about Topaz and how great Topaz PSC is, about 1,200 km2. We have the two fields in Topaz . We have additional running room to look for potential resources, upside resources. 2A is 10 times the size of Topaz , is close to about 12,000 square kilometers. We talk about Kertang, we talk about Kertang is a pre-MMU play, but that's not it. Because of the size of the 2A block, we have so much more potential prospective volumes in the block, especially over on the western, southwestern side of the block.
What you see here in the yellow blobs, those slivers of polygons, those are the Toe Thrust play sitting just to the south, to the west and south of the 2A block. Those are interesting. Those have been left fallow for a while. There's a few wells due in the past by previous operators. You can see just in the map there the two, the tree penetration in this particular place, but with not much success. It's now picking up a lot of interest due particularly to PETRONAS discovery wells sitting just south of our block. Sinsing Machin chang, whom TotalEnergies have just recently signed up to, and according to their press release it could contain up to 4 TCF of resources. This is all within the same play. You can actually see on the map, it's just sitting right next door to these potential 4 TCF resources.
Huge potential, isn't it?
No. That's remarkable. It's the same play, seriously saying the same play that TotalEnergies and Carigali have in the, just to the south of us here, extending up into the southern portion of 2A.
Indeed.
Matthew, also the Kertang itself, we've also focused on Kertang itself being so big, this large Miocene structure, but actually it has a lot of sister prospects to the northwest and east of it as well as to the south.
Indeed.
I think what we've really not talked about publicly before is that there's Kertang itself, but then once Kertang comes in, there's very natural follow on that. You would look to drill, and I think there has to be a focus to the south of the block now as well.
For sure.
Extension of this play from Total, the TotalEnergies PETRONAS Carigali acreage up in the south there. Very exciting
indeed.
Thank you very much, Pierre. Thank you, Matthew. That was fantastic. Clearly it's difficult, we know for investors to get all the nuance of the technical data, but we're trying to give you a flavor of what we've been working on, what we've got, and the excitement we see. Just the highlights, I mean if you didn't hear any of it, please remember these bits. Dewa , very high quality asset. We love the rocks. I think the reservoirs are great. Close to market. EnQuest doing a good job bringing that on. Obviously we are a non-operating partner there, but it's something we did identify and we love, so big tick from us and gives us the diversity that we like in a portfolio with a number of different fields and discoveries. Block 2A, we have a big soft spot for that.
In many ways it's the foundation of Seascape Energy Asia as we know it today. I think you've always got a sense of the excitement we feel around that asset. I think what's different here, there's a couple of new points coming out. First of all, you heard from Matthew, and Matthew is from Sarawak. He's a Sarawakian Earth scientist talking about the biggest Kertang prospect in Sarawak. This is close to home. The other thing to bear in mind here is the follow on. We've always talked about Kertang from day one. We haven't really talked about what's beyond it. INPEX Corporation now operate the block and they're doing a tremendous job, and they are mapping structures which we've seen before, but they're now starting to quantify the upside beyond Kertang, which as Pierre mentioned, we have these lookalikes, much smaller, but surround Kertang.
Now we're seeing this other play, this Cycle V, Cycle VII, what Matthew calls the toe thrust play, where TotalEnergies have come in south of us and they're talking about a 4 TCF development next door in exactly the same play. It continues into our Block 2A. We have that to chase as well. It isn't just the size of Kertang will dwarf everything. When you think about the creaming curve that Pierre talked about, about the yet to find, and we see those big jumps in the creaming curve, it's because things like Kertang get drilled and it pushes the exploration activity out into the North Luconia outboard of where we've seen it so far. Kertang would be a leg up all of its own on that creaming curve on the yet to finds.
If we look at the shallow, the toe thrust, the shallow turbidite play that Matthew and Dr. Pierre were talking about, that again would give you another leg up. Our asset can impact that creaming curve by itself. I mean that's a very, very, very important asset. Topaz is obviously our flagship now, you know, this is our baby. Looking at the Malay Basin side, what we haven't seen in the Malay Basin, there's been a lot of activity Dr. Pierre showed you from the 1970s. You know, it's a well-known, well-explored, well-exploited basin. What we've never seen is someone chase the stratigraphic play on the margins of that basin. There is no reason why it wouldn't work. The geophysics is telling us it should work. Tembakau tells us it should work.
Everything is pointing to quite substantial gas resources sitting there close to infrastructure that we just need to get after with our drill bit. For an impact on a basin, it could be very, very remarkable. For an impact on a company, it's an absolute game changer. This is what I want to leave you with. You may get lost in the seismic, you may get lost in the chronology and the names and everything else. Look, what we've created is something with this resource base, 281 million barrels. What it could lead to on the right is really the thing that I think is exciting. It's great to talk about the seismic and the upside and all the rest, but what does it really mean?
We've got a portfolio here which could deliver north of 40,000 barrels a day of production to this company who today sits at the market cap of £50 million and zero production. That is a huge future. You know, it's all come out of Malaysia, it's all come out of, it's all come out of the geoscience, it's actually all come out of people's heads. It can be translated into hard cash flow and value and that's what our job is. That's what sessions like this is all about. I hope it's been informative. Thank you very much for your attention and I look forward to the next one. Thank you guys.
