Sinopec Confirms Trillion Cubic Meters Of Shale Gas

Sinopec has established the "Xinchang South - Dongxi - Dingshan - Lintanchang" shale gas resource belt in the southeast Sichuan Basin, with a total volume of shale gas resources reaching 1.19305 trillion cubic meters.

This is Sinopec's second trillion-level shale gas reserve after its Fuling shale gas field, which will help to ensure China's energy security.

The 100 billion cubic meters of shale gas reserves in the Xinchang shale gas structure have been confirmed by China Petroleum & Chemical Corporation, which reported on June 30 that it had reached a daily production capacity of 530,000 cubic meters of shale gas in its Xinye Well-1 in Qijiang, Chongqing.

The Xinye Well-1 has a depth of 5,756 meters, and the structure belt has a large favorable area and resources of shale gas, making it a key area for Sinopec's strategic exploration and production of shale gas. The average well depth of the Belt is over 3,500 meters.

In 2017, Sinopec formed a deep shale gas R&D team to pilot research in Dongxi to better understand the challenges of developing deep deposits focusing on complex ground stress and deep burial depth.

The company has developed a theoretical understanding of deep shale gas geology through years of extensive research and practice, and has successfully revealed the development and maintenance mechanism of deep shale holes in deep-water shelf-bathyal facies.

Sinopec is committed to exploring deep shale gas and has developed novel ideas and technologies, such as fracturing for deep shale gas wells, as well as attaining domestic production of fracturing equipment, tools, and materials.

Furthermore, the company has developed deep shale gas layer “sweet spot” prediction technology, which has resulted in high-precision exploration, and deep shale gas fracturing engineering technology, which effectively addresses problems of burial depth and plasticity, as well as high in-situ stress (rock mass stability), to achieve three-dimensional network fracturing technology, which can ensure precision cutting, pressurization, and proliferation, as well as balanced expansion and filling.
