Some CBM reservoirs have extremely low porosity and permeability, which need hydraulic ,fracturing, to achieve greater yields. Furthermore, the reservoir ,fluid, flow gradually changes from single-phase water flow to gas-water two-phase flow during the production process, which can increase seepage resistance and change the form of pressure ...

The pressure of the frack fluid on the target formation causes the target formation to fracture, whilst the proppants in the frack fluid hold open the fractures. This fracturing of the target formation causes the permeability of the formation to be artificially increased and allows the oil and gas to flow more freely back into the wellbore.

9/6/2012, · These chemicals are used in ,fracturing fluid, to break up rocks containing natural gas. The facts currently available do not provide sufficient basis for conclusively assessing potential risks. There is not enough reliable scientific knowledge to identify the specific impact of extracting natural gas from unconventional deposits in Germany, particularly regarding to the potential effects on groundwater.
