Latest Patents
One of Edward W. Sheppard's latest patents is titled "Oil recovery by waterflooding employing an anionic polymeric surfactant." This patent describes a method for recovering oil from subterranean formations by using an aqueous solution of an anionic polymeric surfactant. The surfactant is created by reacting a polymer that includes succinic anhydride moieties with a primary amine. This reaction results in a polymeric product where at least 20 mol percent of the anhydride moieties are converted to succinimide or succinamide groups. The surfactants developed exhibit excellent physical and chemical stability, shear stability, and effectiveness in maintaining the salt stability of other surfactants, such as petroleum sulfonates. They also function as viscosifiers, even in the presence of significant concentrations of divalent metal ions. A preferred form of the invention includes the reaction product of a copolymer of styrene and maleic anhydride with triethylammonium aniline disulfonate, where 20 to 40 mol percent of the anhydride moieties have been converted.
