Chongqing, China (ots/PRNewswire)
Tests confirm significant progress in exploring shale gas at depths greater than 4,000 meters
China Petroleum & Chemical Corporation (HKG: 0386, “Sinopec”) has announced that the key shale gas prospecting, Dongye Deep 2, developed by Sinopec Exploration Company in Dongxi, Chongqing, is being tested daily at a depth of 4,300 meters To produce 412,000 cubic meters of high-quality shale gas.
This success marks significant advances in extra-deep drilling for shale gas at depths greater than 4,000 meters in China. It will increase Sinopec’s shale gas production capacity in southeast Sichuan by over 2 trillion cubic meters. The tested daily shale gas production of 412,000 cubic meters can provide fuel for 820,000 households based on a family of three with a daily gas consumption of 0.5 cubic meters.
After the breakthrough in the Fuling shale gas field in 2012, Sinopec expanded its expertise in the area of deep shale gas deposits. In 2018, Sinopec discovered and commercialized the Weirong shale gas field at a depth of 3,800 meters.
The technical requirements for the development of particularly deep-lying natural gas deposits at depths of over 4,000 meters are high due to the difficulties at extreme depths and the complex crustal stresses. In 2019, Sinopec achieved the breakthrough in fracturing technology for shale gas drilling at depths of more than 4,000 meters with the high-quality Dongye Deep 1 well with a daily production of 310,000 cubic meters.
To develop the Dongye Deep 2 well, Sinopec Exploration Company assembled a deep shale gas research and innovation team to perform technical analysis, including targeting and developing a deep shale gas volumetric fracturing technology to achieve a 100% drilling rate for high quality shale gas to reach. To reduce costs, all Sinopec equipment, tools and materials are made in China.
Next, Sinopec plans to increase oil and gas exploration by developing unconventional resources such as shale oil and gas while specializing in the development of reserves and the production of conventional petroleum.
The company thrives on providing replicable deep shale gas fracking structures that can be advertised. By penetrating to new depths and expanding the achievements of super-deep shale gas exploration and development, Sinopec aims to make a further contribution to the rapidly increasing shale gas production in China.
