China's largest petrochemical products supplier announced on Wednesday that it had achieved a record depth in its ultra-deep oil and natural gas drilling exploration efforts.
The risk exploration well in southwest China's Sichuan Basin registered a depth of 8,866 meters, according to China Petrochemical Corporation (Sinopec).
The landmark well is another example of progress made in the company's ultra-deep drilling project known as Deep Earth. So far the project involves three energy production bases across China.
