CHONGQING, China, July 4, 2022 /PRNewswire=KYODO JBN/ --

China Petroleum & Chemical Corporation (HKG: 0386, "Sinopec") has reported that

it has achieved a daily production capacity of 530,000 cubic meters of shale

gas on June 30 in its Xinye Well-1 in Qijiang, Chongqing, confirming the 100

billion cubic meters of shale gas reserves in its Xinchang shale gas structure.

As of now, Sinopec has established the shale gas resource belt of "Xinchang

South – Dongxi – Dingshan – Lintanchang" (the "Belt") in the southeastern

Sichuan Basin, with overall shale gas resource volume reaching 1.19305 trillion

cubic meters, the second trillion-level shale gas reserve of Sinopec following

its Fuling shale gas field that will contribute to ensure China's energy

security.

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, among which the deepest drilled Dingye

Well-8's shale gas layer has a depth of 4,614 meters.

The challenges of developing deep deposits include complex ground stress and

deep burial depth. Sinopec attaches great importance to exploring deep shale

gas and innovated theories and technologies including fracturing for deep shale

gas wells as well as achieving domestic production of fracturing equipment,

tools and materials. Sinopec has realized 100 percent drilling ration of

high-quality shale.

In 2017, Sinopec established a deep shale gas R&D team to pilot researches in

Dongxi. After years of comprehensive research and practices, Sinopec has built

up the theoretical understanding of deep shale gas geology and successfully

unveiled the development and maintaining mechanism of deep shale holes in

deep-water shelf-bathyal facies.

In addition, Sinopec also proposed deep shale gas layer sweet spot prediction

technology that has achieved high-precision exploration, and developed deep

shale gas fracturing engineering technology that effectively addresses problems

of burial depth and plasticity, as well as high in-situ stress, to achieve

three-dimensional network fracturing technology that can ensure precision

cutting, pressurization, and proliferation, as well as balanced expansion and

filling.

Next, Sinopec will strengthen the precise evaluation of the Xinchang gas field

and elevate the overall evaluation and deployment of the Belt shale gas

resources in southeastern Sichuan, thriving to achieve continuous exploration

breakthroughs.
