The Fuling shale gas field, China's first large commercial shale gas development, has reached a cumulative output of nearly 70 billion cubic meters. This success has propelled breakthroughs in shale gas exploration, expanding the industry across new regions, horizons, and depths.
On October 10, China Petroleum and Chemical Corporation (Sinopec) released a series of achievements, underscoring its commitment to green energy and advanced exploration technology.
Sinopec is accelerating green technology innovation, strengthening the green energy industry, and building a low-carbon circular economy, according to Ma Yongsheng, Sinopec's chairman.
Breaking new ground in shale gas development
Sinopec's shale gas journey began on November 28, 2012, with the Jiaoye 1HF well in Chongqing's Fuling district, producing 203,000 cubic meters of shale gas daily. In the following ten years, Fuling has supplied clean energy to six provinces and two municipalities along the Yangtze River Economic Belt, benefiting over 200 million residents and thousands of enterprises.
With proven shale gas reserves nearing 900 billion cubic meters, Fuling accounts for 34 percent of China's total shale gas reserves. The field maintains a stable annual output of 8.6 billion cubic meters, producing 5.3 billion cubic meters in the first eight months of this year.
To maximize resource recovery, Sinopec has implemented advanced development techniques. By utilizing a multi-layer drilling strategy, the Fuling gas field's recovery rate has doubled to 23.3 percent, with some well groups achieving a recovery rate of 44.6 percent, comparable to international standards.
Since 2018, Sinopec has expanded its exploration efforts into new regions and geological formations, including the successful development of the Weirong deep shale gas field and Nanchuan's atmospheric shale gas.
Pioneering green energy solutions
Beyond shale gas, Sinopec has been actively building a new energy industry system. The company has made Xiongxian in Hebei province China's first "smoke-free city," pioneering a model for geothermal energy development. Sinopec's geothermal projects now cover vast areas across the country. These efforts reduce carbon dioxide emissions by an estimated 4.7 million tons annually.
Last year, Sinopec also launched its green hydrogen plant in Kuqa, Xinjiang. Powered by renewable energy, this facility supplies green hydrogen to nearby chemical plants, reducing reliance on fossil fuels. Since becoming fully operational in August 2023, the plant has participated in electricity transactions equivalent to reducing 147,000 tons of carbon dioxide emissions.
To further its hydrogen energy strategy, Sinopec is expanding its hydrogen refueling infrastructure. The company has built 11 hydrogen supply centers and 136 hydrogen stations across China, focusing on key regions like Shandong and Chengdu-Chongqing.
Leading CCUS technology
Sinopec is also at the forefront of carbon capture, utilization, and storage (CCUS) technology. Its facility in Zibo, Shandong, developed with subsidiaries Qilu Petrochemical and Shengli Oilfield, is China's first million-ton-level CCUS demonstration project.
"The principle of CCUS technology is to capture and purify the carbon dioxide emitted in the industrial process and then put it into the new production process for reuse and storage," said Zhang Chuanbao, Shengli oilfield CCUS reservoir development research senior expert.
Sinopec's continued exploration in CCUS led to a joint research agreement in July 2023 with Shell, Baosteel, and German chemical firm BASF, to assess the feasibility of a 10-megaton carbon storage cluster in east China.
