Formation Stabilizing Fracturing Fluid and Method of Use

A ,fracturing fluid, comprises an aqueous base ,fluid, and a cationic polymer combined with a salt. The ,fracturing fluid, may be used to fracture a subterranean formation. The cationic polymer in combination with a salt provides for reduced clay swelling, while maintaining the granularity and porosity of the formation, which thereby promotes the flow of hydrocarbons from the formation.
