unconventional gas completions

Barnett Shale is the first to be successfully developed in the U.S. shale gas reservoirs is currently the most productive U.S. shale gas field , has become the United States and even other global shale gas field development model. Barnett Shale development using vertical wells early development, but the production is not ideal , after the year 2000 , steering horizontal wells , production has been 3-5 times improved. proppant manufacturers, the U.S. shale gas [ 2 ] , almost all new wells using horizontal wells , depth is usually between 1,200 to 2,500 cubic meters, and the use of long radius of curvature < 10. ~ 157300 > whipstock , measures to facilitate the transformation of late . Generally horizontal section length between 600 to 15,000 , with advances in horizontal well technology operations , the latest horizontal length of more than 30,000 . Most shale wells 611 83 towel horizontal section ends slightly resin coated silica sand heel than 15 ^ 450 > , flowback water and produced water after the birth when it is a good fracturing
