In the oil and gas industries, hydraulic fracturing is a commonly used technique to stimulate hydrocarbon production by creating a network of highly conductive fractures in the area surrounding a wellbore. Recent advances in fracturing technologies, such as multistage fracturing in horizontal wells, are responsible for the latest hydrocarbon production boom in the US. Constraints on local water availability and the potential for damage to formations have led the industry to develop other types of fracturing fluids, such as viscoelastic surfactants and energized fluids. In their review, Reza Barati and Jenn-Tai Liang discuss traditional viscous fluids used in conventional hydraulic fracturing operations, along with the new family of fluids being developed for both traditional and unconventional reservoirs.
