Abstract: A water-based carrier-fluid system comprising a brine formed from water saturated with at least one saturation salt, a viscoelastic surfactant, and one or more salt crystals. The water-based carrier-fluid system is formed by adding the viscoelastic surfactant to the brine to produce a first mixture prior to the one or more salt crystals being added to the mixture. The salt in the salt crystals has a Ksp value equal to or greater than the saturation salt.

Abstract: Friction reducers can be included in a liquid concentrate for use in treatment fluids in oil and gas operations. The liquid concentrate can be a slurry and include oil or a brine as the continuous phase and the friction reducer in dry form as the dispersed phase. The liquid concentrate can be an invert emulsion and include oil as the continuous phase and water and friction reducer dissolved in the water as the dispersed phase. A suspending agent can be included in the liquid concentrate to distribute and suspend the friction reducer throughout the continuous phase. The suspending agent can form micelles that form a mesh-like network to distribute and suspend the friction reducer. A portion of the liquid concentrate can be added to a base fluid at the wellsite to form the treatment fluid. The treatment fluid can be a fracturing fluid.

Abstract: A system comprising a first reactor, a second reactor fluidly connected with the first reactor, and a liquid-solid separator fluidly connected with the second reactor. The first reactor is operable to produce an aqueous bicarbonate solution from captured carbon dioxide (CO2), and an aqueous alkaline solution. The second reactor is configured to produce hydrogen gas and a mixture comprising metal carbonate agglomerates by contacting the aqueous bicarbonate solution from the first reactor with zero-valent metal particulates. The metal carbonate agglomerates comprise a carbonate of the metal on a surface of the zero-valent metal particulates, and the zero-valent metal particulates comprise a zero-valent metal. The liquid-solid separator is configured to receive the mixture from the second reactor and separate the metal carbonate agglomerates from a recovered aqueous alkaline solution.

Abstract: Compositions and methods for treating a well with a treatment fluid. An example method prepares a treatment fluid by combining a furan-based polymer, a Bronsted acid, at least one of an anhydride and/or dibasic ester, a wetting agent, and a docking agent. The treatment fluid is introduced into a wellbore and a wellbore operation is performed with the treatment fluid.

Abstract: A variety of methods and compositions are disclosed, including, in one embodiment, A friction reducer comprising: a continuous phase comprising a base oil and a secondary oil, wherein the secondary oil is different than the base oil; a discontinuous phase dispersed in the continuation phase, wherein the discontinuous phase comprises water and a water-soluble polymer, and an emulsifying surfactant.

Abstract: Systems and methods wherein well-treatment fluids are evaluated for use in a subterranean reservoir. The systems and methods utilize quartz crystals configured to be quartz crystal microbalances (QCM). The QCM has a surface with a reservoir-specific material deposited on the surface. The reservoir-specific material is representative of formation material or proppant. Changes in mass of the reservoir-specific material are measured using the QCM. The changes reflect the interaction of the treatment fluid with the reservoir-specific material and/or hydrocarbons in the reservoir-specific material.
