Acid precursor treatment fluid generating and/or releasing acid for use downhole in a subterranean formation

Abstract

A method includes providing a treatment fluid including a strong acid precursor defined by the structure: where X is independently selected from fluorine, chlorine, bromine, and iodine; where each of R1, R2, and R3 is independently selected from a hydrogen, X, and a C1 to C10 hydrocarbon chain; and where the electron withdrawing group (EWG) is independently selected from a carboxylic acid, carboxylate salt, or carboxylate ester, an orthoester, a sulfonic acid, sulfonate salt, or ester, a phosphonic acid, phosphonate salt, or phosphonate ester, a nitrate, or a cyanide; where Y is hydrogen, a cation, or a C1 to C10 hydrocarbon chain; and wherein each R′ is independently is independently selected from a hydrogen, X, and a C1 to C10 hydrocarbon chain. The method also includes introducing the treatment fluid into a wellbore penetrating a subterranean formation.
