Experimental study shows that the damage rate of fracturing fluid to fracture surface is between 31. 84% and 36. 28%; the damage rate to propping agent layer is between 29. 27% and 30. 04%.

针对太2气层的实验研究表明，压裂液对裂缝壁面的伤害率平均在31.84% - 36.28%之间，压裂液对支撑剂层的伤害率平均在29.27%—30.04%之间。

When the drilling is finished, water, combined with chemicals designed to reduce friction and serve other purposes, is injected from the surface into the well shaft at very high pressures, thereby fracturing the shale rock formations far below, and making it possible to extract economically the natural gas embedded in the shale.

When the high water pressure is released after the fracturing of the shale, some 10 percent to 30 percent of the water comes back to the surface.
