FCF: CNY 15.27 billion, down 69.5% year-on-year, mostly due to bigger E&P input, cash CapEx, and changes in working capital. The company will improve capital management to secure a healthy cash flow that cushions the company's development. For E&P segment, the operating profit was CNY 53.63 billion, up CNY 23.74 billion year-on-year, and remains a major profit contributor. Due to oil and gas product price changes, profit up CNY 9.73 billion. Crude average realized price was $62.85 per barrel, down 4.5% year-on-year. RMB average realized price up 1.6% year-on-year. Due to oil and gas sales changes, profit up by CNY 16.91 billion, in which a bigger oil sales increased profit by CNY 11.14 billion. Bigger gas and shale gas sales increased profit CNY 4.96 billion.
Due to bigger operating expenses and others, profit went down CNY 2.9 billion, in which more purchases led to profit down CNY 12.13 billion. DD&A reduced and profit went up CNY 8.9 billion. For refining and the chemicals segment, the operating profit was CNY 4.97 billion, down CNY 19.7 billion year-on-year. For refining business, the operating profit was CNY 1.38 billion, down CNY 17 billion year-on-year. Due to smaller refining gross profit, profit went down CNY 27.66 billion.

Due to more purchases, services, and others, profit down by CNY 3.54 billion. For marketing segment, the operating profit was CNY 1.897 billion, down CNY 2.6 billion year-on-year. Due to domestic refined oil oversupply, low price realization rate, domestic marketing business saw a loss of CNY 2.099 billion, up CNY 3.15 billion year-on-year, in which a lower gross profit led to profit down CNY 2.1 billion. Operating expenses changes led to profit down CNY 1.06 billion, mostly affected by new leasing criterion. Operating profit from international trading: CNY 3.996 billion, up CNY 0.557 billion year-on-year. For natural gas and pipeline segment, operating profit CNY 18.3 billion, up CNY 2.2 billion or 13.6%. On gas sales, the loss was CNY 1.08 billion, down CNY 1.93 billion year-on-year.

Profit from pipeline transmission: CNY 19.1 billion, up CNY 61 million year-on-year. Profit from city gas: CNY 4.47 billion, up CNY 0.167 billion year-on-year. Less operating expenses led to profit up by CNY 36 million. The return for shareholders has been on our agenda with a stable rate of dividend payout. Since 2016, as oil prices went down, the company has made dividend payment at IFRS-based 45% of net profit to parent company plus special dividend as benefits for shareholders. Therefore, the board recommends an interim dividend of CNY 0.07765 per share at a 50% rate.
As we follow IFRS rules, for 45% of net profit attributed to parent company in first half 2019, CNY 0.06988 per share plus special dividend CNY 0.00777 per share. Next, Mr. Ling Xiao will present the first half 2019 operating performance and outlook for second half 2019.
Thank you, Mr. Chai Shouping. Now, I will brief you on the operation performance of H1-2019 and our outlook for H2. In H1-2019, faced with escalating Sino-U.S. trade frictions, mounting downward pressure in China, large fluctuations of international oil prices, and intensifying market competition, PetroChina adhered to the principle of prudent development and quality development, further cut costs and added profits. Thus, we maintained stable and smooth operation of oil and gas business chains, with production indicators better than expected and performance improving steadily. In first half of 2019, our performance improved steadily.
In China, E&P made many new breakthroughs with stable production growth. Overseas, E&P achieved more results. Major projects are coming online. Progress was made in producing less petrol and more chemicals. Transformation and upgrading picked up pace. Sales structure of oil products was further optimized. International trade saw steady growth. Gas sales climbed in volume and profits. Pipeline network maintained smooth operation. In China, H1 PetroChina sped up E&P, enhanced risk explorations, widely deployed preliminary prospecting, and made 36 achievements. We focused on southwest shale gas, Xinjiang Mahu, and Jimsar, Dagang Oil Field, and other key projects to boost production, which enabled a rebound in oil production and fast-growing natural gas. Especially risk explorations made remarkable breakthroughs.
In Junggar Basin, Gaotan 1 had a daily output of 1.21 thousand cubic meters of oil and 320 thousand cubic meters of gas, a new single well record in classified structure. Total yield during production test was 50 thousand tons. Explorations in deeper layers of southern part were sped up, identifying 30 target traps and planning 50 evaluation wells. In Tarim Basin, Bozi-Dabei found six new gas bearing structures with the potential of trillion cubic meter gas reserve. Comprehensive evaluations in Qiulitage accelerated, also eyeing new discoveries. Petroleum explorations in southern Tahe made new progress and located 33 million tons of 3P reserve. In Changqing Longdong, Qingcheng, Stratum T3YC7, we found the largest shale oil reservoir in China. Newly added P1 and P3 reserve exceed 1 billion tons.
In Volcanics of Western Sichuan, Yongtan 1, fourth section, saw industrial gas flow of 220 thousand cubic meters, with more gas reserve found in the second section, revealing greater potential. In Longnuosi structure, Well Moxi 129H in Stratum Leikou DN4 had a daily production of 1.41 million cubic meters. Thus, the high-quality reservoir in Gaoshiti-Moxi continued to stretch in size. In Songliao Basin, Longping Well 1 produced 115 thousand cubic meters of gas per day. Bedrock explorations in ancient uplift of central north section were very fruitful. Overseas, E&P gained more results, with many major projects coming online. PetroChina sped up independent exploration projects. In Chad, wells in Doseo Basin saw high-yielding oil flows and thick oil layers, hopefully leading to 100 million ton reservoir. In step-fault z one of Southeast Bongor Basin, all six wells proved successful, also promising 100 million tons.
In October, Kazakhstan Central Block in Pre-Caspian Basin eastern slope carboniferous system broke new ground. PK Project in South Turgay Basin made three new discoveries. We also optimized development concepts. Chad 2.2, Halfaya 3, and other key projects went smoothly online. Production overseas grew steadily.
