Abstract: Formation treatment compositions may include a surfactant and an aqueous acid solution or mixture. The surfactant may include one or more of C6-C20-fluoroalkylsulfonate, C6-C20-alkylarylsulfonate, C6-C20-alkylcycloalkylsulfonate, C6-C20-arylsulfate, C6-C20-alkylphosphonate, C6-C20-arylphosphonate, C6-C20-alkylpolyetherphosphate, C6-C20-alkylpolyetherphosphonate, C6-C20-alkylcarboxylate, C6-C20-arylcarboxylate, and polyoxyethyleneamine. In the formation treatment compositions, the surfactant may be configured to partially or fully adsorb on a carbonate formation to accelerate the partial dissolution of the formation. Methods of treating a formation may include introducing the formation treatment composition into a wellbore such that that the formation treatment composition contacts the formation.

Abstract: A stabilized emulsified acid composition for deep carbonate formation stimulation is provided. The stabilized acid emulsion composition includes a petroleum operable to provide a barrier between an acid and a reservoir rock, the acid operable to react with the reservoir rock to dissolve the reservoir rock and produce a wormhole, a functional framework operable to stabilize the stabilized acid emulsion, an emulsifier operable to stabilize the stabilized acid emulsion, and a corrosion inhibitor operable to provide protection against corrosion for the metal components of a well. The petroleum can be diesel. The acid can be hydrochloric acid. The functional framework can be selected from the group comprising surface-modified clay-based material, zeolites, hybrid organic-inorganic materials, covalent-organic framework materials, and boron nitride nanotubes, and combinations thereof. The functional framework can be a surface-modified clay material selected from an organoclay. The corrosion inhibitor is a cationic ammonium-based corrosion inhibitor.

Abstract: A method of fracturing a reservoir comprising the steps of pumping a geopolymer precursor fluid through a wellbore into the reservoir at a fracture pressure, the geopolymer precursor fluid at the fracture pressure generates fractures in the reservoir, wherein the geopolymer precursor fluid is comprised of an amount of aluminosilicate, an amount of alkaline reagent, and a permeability enhancer, allowing the geopolymer precursor fluid to fill the fractures in the reservoir, shutting-in the wellbore at a wellbore pressure, the wellbore pressure maintains the geopolymer precursor fluid in the fractures, allowing the geopolymer precursor fluid to harden for a hardening time to form a geopolymer in the fractures, the geopolymer has a geopolymer matrix, the geopolymer matrix has a permeability, the geopolymer has a compressive strength, and reducing the wellbore pressure allows a reservoir fluid to flow from the reservoir through the geopolymer matrix of the geopolymer to the wellbore.
