    摘要： Sulfonate surfactants are removed from crude oil or crude oil emulsions, such as may be produced using enhanced recovery methods, by mixing with an aqueous solution of synthetic brine such as ammonium chloride, allowing the phases to separate, and removing the aqueous phase containing brine and sulfonates from the organic phase containing hydrocarbons.

    摘要： This invention relates to secondary or tertiary recovery processes for the recovery of oil from subterranean oil-bearing reservoirs. More particularly, this invention relates to an improved method for the recovery of petroleum from underground reservoirs, which petroleum contains sulfonate surfactants and water and for a method of removing said sulfonate surfactants and water from petroleum produced from said recovery processes.

    摘要： Scaling of a production well in a non-carbonate subterranean reservoir is inhibited by injecting into the reservoir the water soluble surfactant metal salt containing a terminal metal ion which is adsorbed on the surfaces of the reservoir and thereafter injecting an inhibitor selected from the group consisting of phosphonates and polymeric carboxylates. The inhibitor reacts with the metal, precipitating as the metal phosphonate or polymeric carboxylate which slowly dissolves in production water to inhibit the formation of scale.

    摘要： Oil and water emulsions can be more rapidly separated when exposed to electromagnetic radiation in the range of from 1 to 300 millimeters, commonly called microwaves. The microwave treatment can be in conjunction with other separating and heating devices such as skimmers, gun barrel treaters, heater treaters, and the like.
