Abstract: Compositions and methods for use in treating hydrocarbon liquids are provided. Specifically, the compositions and methods of the present disclosure relate to additives including betaine and one or more organic acids. In some embodiments, an additive comprising betaine and an organic acid may be added to a hydrocarbon liquid. In certain embodiments, the additive may be added to a hydrocarbon liquid prior to a processing operation.

Abstract: Provided are extraction methods and systems to remove contaminants in a subterranean formation. The method of contaminant removal comprises introducing one or more organic acids and one or more organic acid surfactant boosters into a hydrocarbon-containing stream, recovering the hydrocarbon-containing stream from a subterranean formation, and separating at least a portion of the contaminants from the hydrocarbon-containing stream. The organic acids and the organic acid surfactant boosters have a synergistic effect that improves the contaminant removal efficacy of the organic acid.
