- 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.
