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.

Hydraulic Fracturing | Alberta Energy Regulator

It involves pumping fluid into a wellbore to create enough pressure to fracture the hydrocarbon-bearing rock layer. The fracturing takes place at the start of the wellbore's life cycle. The injected fluid is often water, and it usually contains various chemical additives and a proppant, like sand, to keep the fractures open so oil and gas can flow to the well.
