Selecting a ,fluid, for ,fracturing, is quite important, as the properties need to be dynamic over time. When ,fluid, is initially being injected, the best rate for the ,fluid, entering the formation is achieved when the ,flow, is laminar as this maximizes the energy being distributed to the formation. Turbulent ,flow, is highly

Water-based hydraulic ,fracturing, for the exploitation of shale gas reservoirs may be limited by two main factors: (1) water pollution and chemical pollution after the injection process and (2) permeability decrease due to clay mineral swelling upon contact with the injection water. Besides, shale rock nearly always contains fractures and fissures due to geological processes such as deposition ...
