PetroChina plans to step up shale gas development in Sichuan province with a goal of meeting a third of a 2020 government target for the unconventional resource, according to state media and a government official. The Xinhua news agency reported that the state oil and gas company will increase drilling in southern Sichuan, China’s top gas-producing region and a key early shale development area. PetroChina plans to build 353 Bcf of shale gas production capacity in the province over the next 4 years. For 2017, the company plans to deploy 19 new rigs to drill 110 wells there, part of a total 600 wells planned in the next 4 years, Xinhua said. Domestic rival Sinopec likewise plans to achieve 353 Bcf of shale gas output by 2020.
