PetroChina Shale Gas Drilling Waste Management

As China goverment approved its first shale gas exploration tender, which awarded two blocks in the Sichuan Basin to China Petroleum & Chemical Corp. (Sinopec) and a Henan provincial state-owned company.

PetroChina Co., the country's top-listed gas producer and a subsidiary of the China National Petroleum Corporation. (CNPC), last year started drilling two shale exploration wells in Sichuan province; PetroChina announced earlier its hopes to produce 500 million cubic meters of shale gas by 2015.

During shale gas drilling oil based drilling fluids was used ,while China goverment has strict regulations on drilling waste management since the end of 2013,we feel great honor to participate in the project and make contribution to protect the environment.
