Abstract: This invention concerns introduction of a silicone-containing composition and a liquid hydrocarbon propellant into an oil and gas reservoir. The silicone-containing composition improves the interface between the reservoir fluids and solids facilitating release of natural gas dissolved or entrained in oil and water. The liquid hydrocarbon propellant assists in dispersement of the silicone-containing composition in the reservoir and increases the mobility of the oil by lowering the viscosity of the oil through dilution. The action of the silicone-containing composition improves recovery efficiency through conservation of primary and secondary energy.
