摘要： 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.

摘要： A scale inhibitor squeeze treatment is enhanced by injecting a pre-flush solution into a wellbore, where the pre-flush solution includes at least one organic carbonate solvent, such as a dialkyl carbonate and/or a cyclic carbonate. The use of an organic carbonate solvent can help prevent the pre-flush solution emulsion formation, help avoid water-blocking, and enhance scale inhibitor adsorption. The use of an organic carbonate solvent also permits the pre-flush solution to be free of water, in one non-limiting embodiment.

摘要： Compositions containing a first reactant; an emulsion comprising a surfactant and silicon dioxide (SiO2) nanoparticles; and a carrier fluid containing a second reactant and methods of making. When the first and second reactants react, they generate heat. At a first time, the emulsion surrounds the first reactant, and the carrier fluid with the second reactant surrounds the emulsion. At a second time, the emulsion surrounds a first portion of the first reactant; and a second portion of the first reactant surrounds the emulsion.

摘要： Methods and compositions for enhancing wellbores and propped fractures for use in geothermal operations are provided. In some embodiments, the methods comprise: drilling with a drilling composition at least a portion of a first wellbore, wherein the drilling composition comprises a base fluid, a resin, and a thermally conductive filler; introducing a fracturing fluid into the first wellbore at a first pressure sufficient to create at least a first set of fractures extending from and in fluid communication with the first wellbore; and introducing a first plurality of proppant particulates into at least the first set of fractures, wherein a second wellbore penetrates at least a second portion of the subterranean formation, and wherein a second set of fractures extends from and is in fluid communication with the second wellbore into the subterranean formation, and the first set of fractures is in fluid communication with the second set of fractures.
