Term ,Definition, Hydraulic ,fracturing, Hydraulic ,fracturing, involves the pumping of engineered ,fluids, (referred to as base fluid) at a high pressure into a ,well, that has been drilled to great depths. At the extremities of the ,well, the fluid is forced into target rock where it causes fractures or fissures a few millimetres in diameter. The fissure

16/2/2017, · Thus, hydraulic, fracturing, is used to facilitate entry into the, well, or to improve the gas/oil flow by reopening the pores to bring it to the surface at higher rates. Therefore, the rock is fractured by high pressure or rather, fluids, are pumped into the, well, at pressures sufficient to create cracks in the formation using different types of technologies and, fluids.
