1662701, 166275, 166300, 166371

Abstract:

A method of recovering oil or contaminants from subterranean reservoirs using a surfactant system where an adsorption reducing agent is injected before, after, and/or with the surfactant system. The adsorption reducing agent is formed by the reaction of an olefin sulfonic acid and phenol/aldehyde resin, the structure which is shown below where M may be Hydrogen or any cation, R is hydrogen, alkyl, alkenyl, etc. , X is methylene or other aldehyde derived bridge, Y is hydrogen, ethylene oxide, propylene oxide, butylene oxide or mixtures of two or more of these, x+y is greater than 2 and n is equal or greater than 1.

US Classification:

Abstract:

A process for recovering oil by injecting into a subterranean oil-bearing reservoir through one or more injection wells, an aqueous solution containing one or more amphoteric alkyl amido betaine surfactants that form a viscoelastic gel reducing interfacial tension and increasing the viscosity of the injection fluid simultaneously, displacing the solution into the reservoir, and recovering the oil from one or more production wells. These viscoelastic gels are tolerant to electrolytes and multivalent cations. They are shear reversible and adsorbed little onto the reservoir. Their viscosity is reduced when contacting certain hydrocarbons but remains high when contacting water or brine. This allows the fluid to preferentially penetrate the oil-bearing portions of the formation and resulting additional oil recovery. These viscoelastic surfactant gels are particularly suitable for use with reservoirs and brines characterized by medium to high temperatures, higher salinity, higher concentrations of divalent cations, and low formation porosities.

Abstract:

A method of recovering crude oil from a subterranean hydrocarbon containing formation which comprises (a) injecting into said formation an aqueous solution containing an effective amount alkali metal, alkaline-earth or ammonium salts of alcohol ether sulfonates derived from unsaturated alcohol ethers, and (b) displacing said solution into one or more injection wells and recovering the oil from one or more production wells. The unsaturated alkoxylated alcohol contain various amounts of ethylene oxide, propylene oxide and butylene oxides elected to optimize their interfacial properties with different types of crude oil with different brines.
