Abstract: A process for recovering oil from an oil-bearing formation comprises introducing into said formation an aqueous composition comprising at least one sulfonated derivative of one or more internal olefins, said internal olefins being characterized by having low amounts of tri-substitution on the olefin bond, said sulfonated derivative being obtained by sulfonating a composition comprising internal olefins of the formula: R 1 R 2 C=CR 3 R 4 wherein R 1 , R 2 , R 3 and R 4 are the same or different and are hydrogen or straight- or branched- chain, saturated hydrocarbyl groups and the total number of carbon atoms of R, R, R and R 4 is 6 to 44 with the proviso that at least about 96 mole percent of R 1 and R 3 are straight- or branched-chain, saturated hydrocarbyl groups and at least about 96 mole percent of R 2 and R 4 are hydrogen. Further provided are compositions for use in recovering oil from an oil-bearing formation which comprise the sulfonated derivatives of one or more internal olefins having low amounts of tri-substitution on the olefin bond.
