    摘要： A process to produce a stable suspension of block copolymer particles in a water medium, and a stable suspension of block copolymer particles in a water medium is provided. The block copolymer is a polar functional group-containing vinyl aromatic/conjugated diolefin block copolymer which may optionally be hydrogenated. The use of C.sub.15 to C.sub.24 linear alkyl aromatic sulfonates has been found to be critical in preparation of these stable dispersions.

    摘要： Improved gas foam flooding surfactants and gas foam-forming mixtures wherein the surfactants are enriched in olefin disulfonate. The surfactants may be used in either a gas drive or a gas soak process. Use of the disulfonate-enriched gas foam surfactants and mixtures in a gas flooding operation is also described.

    摘要： An improvement to a steam foam enhanced oil recovery process, whereby the time between injection of a surfactant and the resulting increase in steam injection pressure is reduced by initially injecting a rapidly-foaming surfactant, such as an internal olefin sulfonate, a vinylidene olefin sulfonate, or secondary alkane sulfonate, and subsequently injecting a typical steam foam surfactant that forms foam less rapidly.

    摘要： A process for enhancing the recovery of oil from a subterranean oil-containing reservoir having a temperature of at least about 40.degree. C., which comprises steps for(a) injecting into an injection well in the reservoir substantially liquid CO.sub.2 and an aqueous mixture containing between about 50 and 10,000 parts per million by weight, calculated on the weight of the water, of one or more surfactants of the formulaR--(OCH.sub.2 CH.sub.2).sub.x --Z wherein R represents an alkyl group of about 8 to 16 carbon atoms, x is an integer having an average value of about 5 to 20, and Z represents either a --OCOOM formate group or a --OCH.sub.2 COOM acetate group, with M representing a mono-valent inorganic cation, to displace oil from the reservoir, and(b) recovering the displaced oil from one or more recovery wells in the reservoir.The alcohol ethoxycarboxylate surfactants utilized in this process provide excellent control over the mobility of the CO.sub.2 in the reservoir, and its performance is relatively insensitive to the presence of any of a wide variety of different crude oils.

    摘要： A method of preventing permeability damage due to clay swelling, disintegration and migration in subterranean formations producing oil and gas, where such formations are to be the subject of enhanced oil recovery techniques using anionic or caustic flood chemicals. Prior to the use of such enhanced oil recovery techniques, a cationic organic polymer capable of stabilizing clays is introduced into an oil reservoir treatment area followed by introduction of a sufficient amount of a non-anionic aqueous spacer fluid to cause the cationic organic polymer to reorient itself on the reservoir clays in a substantially monomolecular layer and manner such that it will continue to stabilize the reservoir clays but will not substantially react with the anionic or caustic flood chemicals to form permeability damaging precipitates or to decompose thereby reducing its clay stabilization effectiveness.
