Abstract: A treatment fluid that includes an aqueous fluid, an inorganic acid, and a hydrophobically modified quaternized polysaccharide may be useful in mitigating corrosion of metal surfaces by the inorganic acid. For example, a wellbore operation may include introducing the treatment fluid into a wellbore penetrating a subterranean formation and contacting a metal surface with a treatment fluid.

Abstract: A method of swelling an oil-swellable elastomer in a well comprising the step of: contacting the oil-swellable elastomer in the well with a treatment fluid, wherein the treatment fluid comprises: (A) an oil selected from the group consisting of alkanes and naphtha, wherein the oil comprises hydrocarbons having anywhere in the range of 5 to 21 carbons; (B) an ?-olefin having anywhere in the range of 18 to 26 carbons; and (C) an activator for oil-swelling, the activator selected from the group consisting of: ketones, dodecane, terpenes, terpenoids, haloalkanes having from 9 to 20 carbons, and any combination thereof. An oil-swelled elastomer as produced by the method is also contemplated.

Abstract: Methods and systems for generating heat and/or nitrogen gas in subterranean operations, pipelines, and other related operations are provided. In one embodiment, the methods comprise: providing a treatment composition comprising a carrier fluid, a delayed acid generating component, a first reactant, and a second reactant, wherein the first and second reactants are selected for being capable of reacting in an exothermic chemical reaction or a chemical reaction that produces nitrogen gas; and introducing the treatment composition into at least a portion of a conduit, container, or subterranean formation.

Abstract: A fluid including: (i) a continuous aqueous phase, wherein the continuous aqueous phase has total dissolved solids in a concentration of at least 30,000 mg/l; (ii) an alkyl amido quaternary amine; (iii) a polymer, wherein the polymer is water-soluble or water-hydratable; and (iv) a crosslinker for the polymer. The continuous aqueous phase of the fluid can include a water source selected from the group consisting of flowback water, produced water, and any combination thereof.
