Method of recovering oil using flow stimulating solution
Abstract
Abstract The disclosure of a flow-stimulating liquid solution and methods of use is based primarily on the combination of a linear alkyl sulfonate as a detergent and penetrant, serving as a special carrier for a lauric amide emulsifier to draw oil into emulsion and for a phosphate, as sodium phosphate, to draw water into emulsion. A preservative may be added, as a formaldehyde, as to inhibit deterioration due to bacteria, or other factors. Also when in the course of usage, it may be desirous to quicken the setting action, as by clarifying a floated emulsion, a base, as sodium hydroxide, may be added as a stimulant to break the emulsion. The solution may be used in recovering oil from an oilbearing formation, or in reclaiming contaminated or used oil.
