Abstract:
In one embodiment, the present technology provides a surfactant composition comprising an imide compound in an optional solvent for use in a hydrocarbon base fluid to improve the emulsification of an acidizing agent in the hydrocarbon base fluid. In another embodiment, the present technology provides a method of employing an acidizing well-bore stimulation fluid containing the surfactant composition to stimulate a reservoir.
