Patent number: 8759261Abstract: The present invention provides a method of treating a hydrocarbon containing formation comprising (a) providing a hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation, wherein the composition comprises one or more internal olefin sulfonates having 17 or more carbon atoms, (b) adding water and/or brine from the hydrocarbon formation to the composition, (c) adding a solubilizer which comprises an ethoxylated alcohol wherein the alcohol before ethoxylation had an average molecular weight of at least about 220 and (d) allowing the composition to interact with hydrocarbons in the hydrocarbon containing formation. The solubilizer may comprise less than about 0.1 wt %, preferably from about 0.02 to about 0.05 wt %, of the total composition and it may have from about 5 to about 9 moles of ethylene oxide per mole of alcohol.Type: GrantFiled: February 5, 2009Date of Patent: June 24, 2014Assignee: Shell Oil CompanyInventors: Julian Richard Barnes, Kirk Herbert Raney, Thomas Carl Semple, Paul Gregory Shpakoff, Johan Paul Smit, Jasper Roelf Smit
