    Abstract: A method of reducing corrosion within a wellbore includes placing a wireline including a perforating gun in a wellbore, the wellbore extending through an earth formation and including a casing extending through the earth formation, the wireline including zinc, discharging the perforating gun to form perforations through the casing and in the earth formation surrounding the casing proximate the at least one perforating gun, flowing a fracturing fluid including one or more proppants through the perforations and into the earth formation to open fractures in the earth formation with the one or more proppants, introducing a flushing fluid into the wellbore to displace the fracturing fluid, and flowing a corrosion inhibitor composition into the wellbore and through the perforations with at least one of the fracturing fluid and the flushing fluid. The corrosion inhibitor includes an alkenylphenone, and a substituted 1-azanapthalene. Related methods of inhibiting corrosion are also disclosed.

    Abstract: An aqueous solution is disclosed including water, an acid, a nitrogen-containing compound, and a functionalizing agent (FA), which can be a ketone, diketone, aldehyde, dialdehyde, organic acid, and combinations thereof. An additional aqueous solution is disclosed including water, an acid, and an acid neutralizing agent which can be a reaction product of at least a portion of the nitrogen-containing compound and the functionalizing agent. Methods of treating a formation are also disclosed including treating a formation fluidly coupled to a wellbore with an oilfield treatment fluid comprising either or both of the aqueous solutions.

    Abstract: The present disclosure is directed to an apparatus having a separator and mixing equipment. The separator is operable to receive exhaust from fuel-burning equipment at a wellsite and separate the exhaust into a gas component and water. The mixing equipment is operable to receive at least one of the gas component and the water to form a subterranean formation treatment fluid. The present disclosure is further directed to a method of operating fuel-burning equipment at a wellsite to form an exhaust and utilizing the exhaust to form a fluid for injecting into a wellbore to treat a subterranean formation into which the wellbore extends.

    Abstract: Methods include combining an amount of water and an acid retarding agent (RA), where the amount of water is present in an amount up to about 5 times the mass of the RA, inclusive, and wherein the RA includes at least one salt compound. An amount of acid is dissolved in the combined amount of water and RA to form a composition, where the amount of acid is a molar ratio of acid:RA of between 4.0 and 0.2, inclusive, and wherein the amount of acid is up to about 36% by weight of total weight of the composition. The composition is injected into a wellbore penetrating a subterranean formation at a pressure, which may be less than the fracture initiation pressure of the subterranean formation in some cases, while in other cases equal to or greater than the fracture initiation pressure.
