Abstract
A method of preparing a fracturing fluid for hydraulic fracturing in unconventional reservoirs such as coal beds, sandstones, and shales. The method includes selecting an anionic surfactant, such as an anionic sulphonate surfactant; and contacting the anionic surfactant with a fracturing fluid or with a precursor of said fracturing fluid. The fracturing fluid may further include friction reducing polymers and a booster formulation that provides enhanced polymer performance for increased friction reduction as well as faster polymer dissolution in the fracturing fluid.
