Fracturing Fluid Flowback, and In-Situ Distribution in Unconventional Reservoirs. During hydraulic ,fracturing, treatments, a large amount of ,fracturing fluid, is injected into the tight subsurface formation. However, only a small portion of injected ,fluid, can be recovered during the ,flowback, process.

API | How much water does hydraulic fracturing use?

How ,much water does hydraulic fracturing use,? The average fracking job uses roughly 4 million gallons of water per well – or about as much water as New York City uses every six minutes and about 1.3 percent of the water used by the country’s car washes every day.That can vary by state, because the amount of water used in each hydraulic ,fracturing, job depends on geology and a …

After the fracturing and shut-in periods, shale gas wells go through a process of flowback to return the injected fracturing water before production. Recent studies suggested that the rate and pressure data recorded during flowback can provide a very early opportunity to characterize fracture network after the fracturing treatment [ 31 , 32 , 33 ].

Under the same injection volume, the fracturing fluid recovery is higher when the fracture geometry is planar. Fluid recovery is relatively lower whenever natural fractures are activated during fracturing treatments; flowback time is also shortened when complex fracture network with enlarged fracture interface is present.
