Abstract: Described herein is a low-temperature catalyst and method of use for causing an exothermic reaction in a low temperature environment. The mixture can include sodium nitrite, an ammonium-based compound, and an oxidizer and can be injected into a fluid flow path. The fluid flow path can be a pipeline, a flowline, a wellbore, or a subterranean formation. The mixture can cause an exothermic reaction in the fluid flow path and remove, using the exothermic reaction, a damaging material from the fluid flow path.

Abstract: Various embodiments disclosed relate to acidizing compositions and methods of using the same for treatment of subterranean formations, wherein the acidizing compositions comprise an acid; and a compound having a structure chosen from: Formula (I, II), wherein R1 at each occurrence is independently chosen from —H and substituted or unsubstituted (C1-C30)hydrocarbyl, R2 at each occurrence is independently chosen from —CN, CONRA2, and —COORA, wherein RA at each occurrence is independently chosen from —H and substituted or unsubstituted (C1-C30)hydrocarbyl, R3 at each occurrence is independently chosen from substituted or unsubstituted (C1-C30)hydrocarbyl, a substituted or unsubstituted (C1-C10)heterocyclyl, and a (Ci-C3o)hydrocarbyl substituted by a substituted or unsubstituted (C1-C10)heterocyclyl and interrupted by 0, 1, 2, or 3 groups independently chosen from -0-, —S—, and substituted or unsubstituted —NH—, and M is a Michael-addition donor.

Abstract: Methods for acidizing subterranean formations may include introducing into a wellbore penetrating the subterranean formation having a temperature of about 275° F. or greater a treatment fluid comprising an aqueous fluid, a Lewis acid catalyst and a precursor; wherein the precursor is selected from the group consisting of a saccharide, a saccharide derivative, and a combination thereof; and reacting the precursor and the Lewis acid catalyst to yield an organic acid in a portion of the subterranean formation, a portion of the wellbore, or both.

Abstract: Methods of treating a subterranean formation penetrated by a wellbore of a well, wherein the subterranean formation includes carbonate. The methods can include the following steps of: (1) optionally, fracturing the subterranean formation; (2) optionally, acidizing the subterranean formation with a Bronsted-Lowry acid; (3) treating the subterranean formation with an acid-producing microorganism, a nutrient for the microorganism, and, if needed, a suitable electron acceptor for respiration by the microorganism; (4) optionally, flushing the wellbore with a wash fluid to push the microorganism deeper into the subterranean formation and wash it away from the metal tubulars of the well; (5) preferably, shutting-in the well for a required incubation period for in-situ acid generation by the microorganism; and (6) preferably, after the shut-in, flowing back fluid from the subterranean formation into the wellbore.
