摘要： Additional amounts of crude oil are recovered from a subterranean formation by flooding with a translucent emulsion comprising an upper- or middle-phase microemulsion as an external phase and a polymer-containing brine solution as an internal phase. The translucent emulsion tends to coalesce into its component phases under conditions of no shear, but is stabilized by low shears such as those imposed on fluids flowing through a subterranean formation.

摘要： A method of enhanced oil recovery is disclosed wherein an upper-phase or a middle-phase microemulsion and an immiscible aqueous phase are simultaneously injected into a subterranean formation. The viscosities of the injected phases are adjusted so that the aqueous phase/microemulsion viscosity ratio approximates the reservoir brine/oil viscosity ratio. The injection rates of the injected phases are such that similar oil, microemulsion and aqueous phase velocities are achieved in the reservoir. Oil is displaced to a production well and recovered.

摘要： An oil recovery method is disclosed which uses a particular class of alkylaryl sulfonate surfactants. The surfactants are derived from an extracted aromatic feedstock consisting essentially of benzene, toluene, xylenes, and lesser amounts of ethylbenzene, trimethylbenzenes, and tetramethylbenzenes. The aromatic feedstock is then alkylated with linear .alpha.-olefins to favor second-carbon attachment, and sulfonated to result in surfactants having high oil solubilization parameters and whose phase behavior is substantially independent of temperature over 120.degree.-250.degree. Fahrenheit.

摘要： A method for recovering oil from a subterranean formation is disclosed wherein an aqueous surfactant solution is injected into the formation to reduce the mobility of gas in a gas-flooding process. The gas may include hydrocarbon gas, inert gas, carbon dioxide, and steam, or mixtures thereof.
