Lpg micellar solutions as fracturing fluids

Abstract

Abstract A fracturing fluid successfully useful for stimulating gas producing wells is obtained by mixing 60-95 percent by volume of a hydrocarbon containing an average of C-3 to about C-10 carbon atoms, up to 20 percent by volume of water, 2.5 to about 25 percent of a surfactant obtained by condensing about 1 mole of an alcohol containing about 4 to about 20 carbon atoms with about 1 to about 20 moles of an alkene oxide to obtain a surfactant having a HLB (hydrophil-lipophil balance) of about 3 to about 15, and optionally containing 0.1 to about 10 percent by volume of a cosurfactant which can be an alcohol containing 1 to about 10 carbon atoms and/or about 0.001 to about 5 percent by weight (based on aqueous medium) of an electrolyte. In addition, the fracturing fluid can contain propping agents, fluid loss control agents, corrosion inhibitors, diverting agents, and other additives desired for a particular fracturing process.
