| titleOfInvention | Ether sulfoxide compounds for enhanced oil recovery |
| abstract | A process for recovering crude oil from a subterranean formation comprising injecting into the formation a liquid composition consisting essentially of a specific surfactant in an aqueous medium, driving the liquid composition through said formation to displace oil from said formation and recovering said oil in a production well. The surfactant has the general formula <IMAGE> wherein R1=C1-C30 alkyl or alkylaryl, R2=C2H4 or C3H6, R3=C2H4 or C3H6, R4=C1 to C12 alkyl or alkylaryl, R5=H or C1-C12 alkyl or alkylaryl, x and y are integers from 0 to 100, and z is an integer from 1 to 4. |
