16/4/2020, · Thus, the fracturing-fluid properties are very important in the creation and propagation of the fracture. Properties of a fracturing fluid. The ideal fracturing fluid should: Be able to transport the propping agent in the fracture; Be compatible with the formation rock and fluid; Generate enough pressure drop along the fracture to create a wide fracture

Hydraulic fracturing by country - Wikipedia

Fracking has been in common use by the petroleum industry in Canada since at least the mid-1960s. Massive hydraulic ,fracturing, has been widely used in Alberta since the late 1970s to recover gas from low-permeability sandstones of the Spirit River Formation. The method is currently used in development of the Cardium, Duvernay, Montney and Viking in Alberta, Bakken in Saskatchewan, Montney and ...

Monitoring Fracturing Fluid Flowback With Chemical Tracers ...

Fracturing fluids are used to both prop open a fracture and to effectively carry the proppants and place them into a fracture and to successfully flowback to the surface. Productivity of a well, after proppant placement, greatly depends on the flowback efficiency.

Fracturing-fluid flowback in hydraulically fractured gas shale is a complicated transport behavior involving hydrodynamic (H), mech. (M) and chem. (C) processes. Although, many flowback models have been published, none of the models flly coupled the transient fluid flow modeling with chem.-potential equil. and fracture closure phenomena.
