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.

Catalyst for exothermic reaction in a wellbore

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 Rat each occurrence is independently chosen from &#x2014;H and substituted or unsubstituted (C-C)hydrocarbyl, R2 at each occurrence is independently chosen from &#x2014;CN, CONR, and &#x2014;COOR, wherein Rat each occurrence is independently chosen from &#x2014;H and substituted or unsubstituted (C-C)hydrocarbyl, Rat each occurrence is independently chosen from substituted or unsubstituted (C-C)hydrocarbyl, a substituted or unsubstituted (C-C)heterocyclyl, and a (Ci-C3)hydrocarbyl substituted by a substituted or unsubstituted (C-C)heterocyclyl and interrupted by 0, 1, 2, or 3 groups independently chosen from -0-, &#x2014;S&#x2014;, and substituted or unsubstituted &#x2014;NH&#x2014;, and M is a Michael-addition donor. 

Composition for treatment of subterranean formations

Methods for acidizing subterranean formations may include introducing into a wellbore penetrating the subterranean formation having a temperature of about 275&#xb0; 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.

Acidizing fluids and methods for use in subterranean formations

Various embodiments disclosed relate to compositions for treating subterranean formations including an aluminum trihalide hexahydrate and methods of using the same. In various embodiments, the present invention provides a method of treating a subterranean formation including obtaining or providing a composition that includes an aluminum trihalide hexahydrate. The method also includes placing the composition in a subterranean formation.

Subterranean treatment with compositions including hexaaquaaluminum trihalide

Controlling fluid flow in a subterranean formation containing water and hydrocarbons utilizing a Gemini surfactant introduced to the formation via a wellbore. The Gemini surfactant includes a head group having two cationic groups linked by an alkyl spacer, an amide extending from each of the cationic groups, and each amide having a hydrophobic tail extending therefrom.
