Abstract: An acid corrosion inhibitor includes an active corrosion intermediate including alkylated pyridine, an internal intensifier including formic acid, a filming additive including cinnamaldehyde, a surfactant including one or more of propylene glycol methyl ether and alcohol ethoxylate, and a solvent including ethylene glycol. A system includes a formulation, an acid system including HCl and MSA, and a metal surface contacting the formulation and/or the acid system. The formulation of the system includes an alkyl pyridine, formic acid, cinnamaldehyde, and one or of propylene glycol methyl ether and alcohol ethoxylate. A method for reducing corrosion of a pipe in contact with an acid system and disposed in a well bore includes applying the acid corrosion inhibitor. The acid system includes methanesulfonic acid.

Abstract: The present application describes compositions and methods for inhibiting acid corrosion.

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.
