Patent
·
OSTI ID:6126294
Production of formation fluids through a well bore from a formation having a water and hydrocarbon emulsion blockage surrounding the well bore is restored by injecting from about 0.01 to 10 bbl per vertical ft of formation of micellar dispersion into the formation, to solubilize the emulsion. The micellar dispersion is composed of hydrocarbon, aqueous medium, and surfactant. (20 claims)
