SOE forges on with shale oil extraction

The second drilling unit of CNPC Greatwall Drilling Co completed a drilling task in the Gulong shale oil formation in Daqing, Heilongjiang province, in late September, laying a solid foundation for the efficient extraction of shale oil from Daqing Oil Field.

The company — a unit of State-owned China National Petroleum Corp — completed the project in 20 days, achieving a section depth of 3,065 meters.

As an important energy source, the development and utilization of shale oil can significantly alleviate the pressure on China's energy consumption and reduce its dependence on foreign oil.
