Hydraulic ,fracturing, requires a large volume of fresh water, which is difficult and expensive to obtain in the desert area such as Tarim Basin. Currently, ,flowback fluid, is typically transported to the sewage treatment plant and then discharged after reaching environmental requirements; however, this is not only costly, but also a waste of water resource.

Once the fractures have been created, injection ceases and the fracturing fluids begin to flow back to the surface. Materials called proppants (e.g., usually sand or ceramic beads), which were injected as part of the frac fluid mixture, remain in the target formation to hold open the fractures.

per well. Hydraulic fracturing involves pumping large volumes of fluid blended with proppant and chemicals at pressures necessary to fracture a hydrocarbon-containing formation. Once the fractures are created, proppants are placed within the fractures to hold them open and allow for the release and flowback of fluids and hydrocarbons.

Petropedia - What is Flowback? - Definition from Petropedia

Flowback, is very much associated with producing natural gas or shale gas through shale rocks using horizontal drilling and hydraulic ,fracturing,. It is recovered from the well at the surface when the ,fluid, is used to hydraulically fracture the shale formations. ,Flowback, is considered to be an important step in drilling operations.

1/10/2020, · Therefore, in field, the fracturing fluid flowback time should be shortened as much as possible to reduce the soaking effect of the gel breaking fluid on the proppant. (3) The damage of the conductivity caused by the crush and embedding of the proppant showed that the potential rock/fluid reaction between the gel breaking fluid and the formation has a certain influence on the proppant embedding.

Fracking Fluid & Flowback The name “hydraulic fracturing” suggests the involvement of water in the drilling process, but fracking fluid actually contains more equally important ingredients: Water – This is the most important element. Up to millions of gallons are sunk in each well, as the water is responsible with the actual fracturing.

Following a fracturing event, the fracturing fluid withdrawn from the well is termed flowback and consists of the original fluid plus additional components that have been mobilized from the shale layer such as salts, metals, and radioisotopes. The high levels of dissolved salts leached from bedrock are a challenge to analyzing fracking

As the fracturing process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the fracturing fluid to deactivate the gelling agents and encourage flowback. Such oxidizers react with and break down the gel, reducing the fluid's viscosity and ensuring that no proppant is pulled from the formation.
