How fracking fluid is used with shale gas
How fracking fluid is used with shale gas

Fracking fluid is used as injection and fracture rocks allowing the recovery of shale gas from areas where otherwise it could not be recovered. There is much debate as to whether the backflow from fracking fluid affects groundwater and endangers the health of area residents.

Elasticity-Driven Backflow of Fluid-Driven Cracks - NASA/ADS
Elasticity-Driven Backflow of Fluid-Driven Cracks - NASA/ADS

Fluid,-driven cracks are generated by the injection of pressurized ,fluid, into an elastic medium. Once the injection pressure is released, the crack closes up due to elasticity and the ,fluid, in the crack drains out of the crack through an outlet, which we refer to as ,backflow,.

The backflow of fracking fluids is often disposed of by injection in well sites with large underground areas that are sealed by impermeable rock layers. Disposal wells are operated by many energy companies, and there have not been many incidents caused by chemical migration to – or contact with – aquifers.

The effect of the "amphiphobic surface" on the ,backflow, efficiency ,of fracturing fluid, was measured by permeability impairment test with dense sandstone cores. Testing results showed that FCS generated a tight molecular film on the surface of the sandstone cores, turning the surface of the sandstone cores to an "amphiphobic surface", with angles of contact for both oil and water greater than 90°.

Hydraulic fracturing (also called as fracking, fracing, hydrofracturing) involves high-pressure injection of ‘fracing fluid’ (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely.
