In a method of hydraulically fracturing a hydrocarbon-bearing subterranean formation, a proppant stage is introduced into the fracture which contains a gaseous fluid and an ultra lightweight proppant suspended in a viscosified aqueous fluid. The gaseous fluid of the proppant stage contains at least about 90 volume percent of the combination of gaseous fluid and aqueous fluid. A pad fluid may first be introduced into the formation, the pad fluid containing a gaseous fluid and, optionally, an aqueous fluid. The gaseous fluid of the pad fluid mixture typically contains at least 70 volume percent of the mixture.

Method of fracturing using ultra lightweight proppant suspensions and gaseous streams

A low viscosity fluid for reducing fluid loss in a relatively low permeability formation has a viscosity of less that 10 CP and contains a low molecular weight viscosifying agent The aqueous medium may be fresh water, salt water, brine or slickwater. The invention has particular applicability when an ultra lightweight (ULW) proppant or sand control particulate is employed. The fluid may be used in reservoirs having a relative permeability less than 10 mD.
