caused by ,fracturing fluid, invasion is called ‘fracture-face damage’ and it is believed to aggravate during shut-in time. Therefore, the objective of this investigation is to quantify ,gas production, impairment due to spontaneous migration of ,fracturing fluid, into ,shale, formations, as a function of shut-in time.

Estimating the Fracturing Fluid Recovery in Shale Gas ...

In ,shale gas, reservoirs, the ,fluid flowback, rates have become one of the key parameters to evaluate the ,fracturing, operation and manage ,fracturing fluid, after well stimulation. Based on experimental tests and a field data analysis, this paper proposed a method to estimate the ,fracturing fluid, recovery. First, ,fracturing fluid, imbibition and ,flowback, experiments were conducted with fractured ...

Accordingly, the rocks containing unconventional gases need to be fractured through external pressure. In cases of shale gas exploration, a series of wells (sometimes, horizontal as well as vertical) is dug to reach the rock containing shale gas, and through the wells pressurised water, mixed with chemicals, is injected to fracture the rocks.

Hydraulic fracturing - Wikipedia

Hydraulic fracturing of shales goes back at least to 1965, when some operators in the Big Sandy gas field of eastern Kentucky and southern West Virginia started hydraulically fracturing the Ohio Shale and Cleveland Shale, using relatively small fracs. The frac jobs generally increased production, especially from lower-yielding wells.
