Abstract
A method of recovering hydrocarbons from subterranean reservoirs by the use of a viscous microemulsion form the single phase region of the ternary diagram of a microemulsion system that is optimal at the reservoir salinity is disclosed. The microemulsion is obtained by first determining the reservoir salinity and viscosity, then determining the oil molar volume that corresponds to a microemulsion having the reservoir viscosity, then determining the oil or mixture of oils that correspond both to the oil molar volume determined above and the reservoir salinity. The oil is then used to create a microemulsion within the single phase region of an optimal microemulsion.
