high density ceramic of proppants made of sintered bauxite proppant creates a problem

It has been recognised that the high density ceramic of proppants made of sintered bauxite proppant creates a problem in the placement of the material. This arises from the fact that the fluid used to transport the proppant requires modification from that used to transport for example, resin coated silica sand because of the substantially greater tendency for particles of sintered bauxite to settle more rapidly from the suspension. This increases the cost of placing the proppant but an even greater cost penalty results from the higher density by comparison with that of silica sand. It will be immediately obvious that a proppant with density of 3.7, which is typical of sintered bauxite presently used, will require a greater mass of material to fill a fracture of given volume than proppant with density of 2.65.

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 .
