BEIJING, Dec. 15, 2021 /PRNewswire/ -- China Petroleum
& Chemical Corporation's (HKG: 0386, "Sinopec") has reported
another strategic breakthrough of shale oil exploration. This time,
its subsidiary Sinopec East China Petroleum Bureau has recorded
high-yield shale oil flow in three prospecting wells in Subei
Basin. Among which, the Qinye 1HF well has tested daily oil
production of 55 tons, the Shuaiye 3-7HF well has tested 20 tons
per day, and the previous deployed Shaduo 1 well has a cumulative
production of 11,000 tons over 392 days of continuous flow.
Preliminary evaluation shows that Sinopec's establishment of a
420-square-kilometer favorable area with 350 million tons of shale
oil resources in the Qintong sag has exhibited good prospects for
exploration and development in the region and will inaugurate crude
oil resources strategic replacement in China's Subei Basin.
The shale oil in the Subei Basin has a burial depth of more than
3,000 meters, where development is difficult as the pressure is
high and the storage space is thinner than a hair, bringing great
challenges to processing techniques like drilling and fracturing.
Sinopec East China Petroleum Bureau has achieved this major
breakthrough in shale oil exploration by combining the actual
exploration facts of Subei Basin to strengthen research on
formation conditions and enrichment patterns of continental shale
oil.
Sinopec has continued to expand and further its exploration
efforts of shale oil. In January
2021, Sinopec Exploration Branch conducted test production
of Taiye 1 well of shale oil and gas, preliminary estimation has
showed shale gas reserves of 200 billion cubic meters and
condensate of 280 million tons.
In November 2021, Sinopec Shengli
Oilfield achieved a major breakthrough of shale oil exploration in
the East Exploratory Area, the first batch of shale oil geological
reserves has reached 458 million tons by current predictions.
Initial estimates of shale oil resources in the region amount to 4
billion tons, making it a new frontier for increasing reserves and
production in eastern China.
In the exploration and development of shale gas, Sinopec
established China's first
10-billion-cubic-meter major shale gas field, the Fuling shale gas
field which has produced 40 billion cubic meters of shale gas
cumulatively. As of now, the shale gas field has proved new
reserves of 104.883 billion cubic meters, making the cumulative
total to reach 900 billion cubic meters which accounts for 34
percent of the total proved shale gas reserves in China.
In addition, Sinopec discovered China's first deep shale gas field, the
Weirong shale gas field, the first phase of which has built a
production capacity of 1 billion cubic meters in 2020.
