The “choking” effect produces back pressure in the casing, which allows simultaneous entry of fracturing fluid into multiple zones of varying in situ stress states. Treatment distribution among zones can be controlled to a degree.

The hydraulic fracturing fluid shifts the pressure created into the groundwater to build fractures in the rock formations of the reservoir and to hold and position the proppant in the splits so that they stay “propped” exposed after the injecting pressure is turned off (Koplos, Tuccillo, and Ranalli).

The engineering structure of the hydraulic fractures allows the water to ,flow back, to the surface once pumping stops. It is also ensures that the fractures remain open for the gas to ,flow,. Thus, besides water being the primary ,fluid, for ,fracturing,, it supports the engineering work to create an efficient process.

1/12/2020, · Hydraulic ,fracturing,, ... This forces the ,fluid, into the cracks and crevices of the shale where natural gas is trapped. Because of the immense internal pressure, the petroleum-rich (or gas rich) ,fluid, flows ,back, up to the surface of the well and collects in a tank. Expand.

Flowback is the portion of the injected ,fracturing fluid, that flows ,back, to the surface, along with oil, gas, and brine, when the well is produced. An estimated 90% of flowback in the United States is disposed of into deep EPA-licensed Class II disposal wells , with the remaining less than 10% reused, evaporated, used for irrigation, or discharged to surface streams under an NPDES permit.

21/12/2015, · As a result of this extensive fracture propagation, the fracturing fluid has a lot of room to occupy and so, it relaxes some of its high pressure and the fluid pressure drops substantially. There is another reason for pressure drop: the unevenly distributed pressure in the previous immature fracture is now re-distributed much more uniformly in the current wide and long fracture.

Fracturing fluid, migration is a multiphase ,flow, problem in which gas or oil (the nonwetting phase) contained in the shale interacts with HF ,fluid, or brine (the wetting phase). Most shale gas plays have low brine saturation (0.1–0.5), which gives rise to a number of multiphase ,flow, effects such as capillary imbibition and reduced relative permeability [ Byrnes , 2011 ; Engelder , 2012 ].
