CHONGQING, China, Nov. 1,2021/PRNewswire=KYODO JBN/--

- Tests confirm significant progress in deep shale gas exploration at a depth

of over 4,000 meters

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

that the Dongye Deep 2 key shale gas prospecting well developed by Sinopec

Exploration Company in Dongxi, Chongqing, with a buried depth of 4,300 meters,

has been tested to produce 412,000 cubic meters of high-quality shale gas daily.

At a depth of more than 4,000 metres, the achievement marks significant

progress in ultradeep shale gas exploration 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's 0.5 cubic

meter daily gas consumption.

Following the breakthrough of the Fuling shale gas field in 2012, Sinopec has

been expanding its expertise in deep shale gas. In 2018, Sinopec discovered and

commercialized the Weirong shale gas field at a depth of 3,800 meters.

The technical requirements of developing deep marine shale gas reservoirs at

depths of over 4,000 meters are high due to challenges faced at ultra-high

depths and complex crustal stress. In 2019, Sinopec achieved the breakthrough

of fracturing technology for shale gas wells 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 put together a

deep shale gas research and innovation team to conduct technical analysis,

including target evaluation and developing deep shale gas volumetric fracturing

technology to achieve a high-quality shale gas drilling rate of 100 percent. To

reduce costs, all of Sinopec's equipment, tools, and materials were

manufactured in China.

Next, Sinopec plans to devote greater effort to increase oil and gas

exploration by developing unconventional resources such as shale oil and gas

while focusing on growing reserves and production of conventional petroleum.

The company thrives on providing replicable deep shale gas fracturing

construction that can be promoted. By breaking through to new depths and

expanding the achievements of deep shale gas exploration and development,

Sinopec is committed to making further contributions to the rapidly increasing

production of shale gas in China.
