Shale gas exploration and development technology and equipment are basically localized

At the "Shale Gas and Ecological Environment" forum held on June 28, Li Jin, deputy director of the China Geological Survey of the Ministry of Land and Resources, said that the technology and equipment for shale gas exploration and development have basically been localized.

According to the Xinhuanet news on June 28, Li Jinfa said that at present, the shale gas geophysical, drilling, fracturing and gas testing technologies have been mastered. The drilling cycle of horizontal wells has been reduced from 150 days to 70 days, the shortest. In 46 days, the cost of a single well in a horizontal well fell from 100 million yuan to 50 million to 70 million yuan.

Li Jinfa introduced that in recent years, the National Development and Reform Commission, the Ministry of Finance, and the National Energy Administration have successively issued a number of encouragement and support policies to include shale gas in development planning, and strive to produce more than 30 billion cubic meters of shale gas by 2020.

According to the China Geological Survey data, as of the end of 2014, shale gas has newly added proven geological reserves of 106.75 billion cubic meters, and in 2014 produced shale gas of 1.3 billion cubic meters.
