  • Patent number: 10435620
    Abstract: Provided are acidic treatment fluids comprising a weakly emulsifying surfactant, an aqueous base fluid, and an acid. In some embodiments, the treatment fluids are capable of forming short-lived oil-in-acid emulsions due, at least in part, to the interaction of at least a portion of the weakly emulsifying surfactant with one or more oil or gas molecules within a subterranean formation.

  • Patent number: 7300906
    Abstract: Sulfhydryl odors in organothiophosphate formulations are suppressed by treatment of the thiophosphate compound (e.g., bensulide) during preparation of the formulation with a selected emulsifier agent, ethoxylated tallow amine. The amine and any reacting products resulting from the treatment are retained in the final formulation. The amine will continue to react with the mercaptan and other sulfhydryl compounds formed by the continuing degradation of the thiophosphate compound, thereby providing further odor control.

  • Patent number: 5580841
    Abstract: Disclosed are solid, phytoactive, N-phosphonomethyl-N-carboxymethyl compositions. Also disclosed are processes for the preparation of such compositions by(a) forming an initial mixture comprising a phytoactive N-phosphonomethyl-N-carboxymethyl compound, a solvent and a molten surfactant, the surfactant being solid at ambient temperatures;(b) removing solvent from the initial mixture to form a final mixture at a temperature above the melting point of the surfactant;(c) cooling the final mixture to a temperature below the melting point of the surfactant to form a N-phosphonomethyl-N-carboxymethyl composition which is solid at ambient temperatures; and(d) processing said composition into particulate form, such as pellets, flakes, granules, or powders.
