A process is given of recovering hydrocarbon from a subterranean formation having at least one injection means in fluid communication with at least one production means and wherein a micellar dispersion comprised of water, hydrocarbon, cosurfactant, electrolyte and petroleum sulfonate obtained by sulfonating whole or topped crude oil is injected into the formation and displaced toward the production means to recover hydrocarbon therethrough, the improvement comprising incorporating amounts of the cosurfactant into the micellar dispersion in excess of the amounts required to cause the micellar dispersion to go through a maximum viscosity and to establish a desired viscosity for the flooding of the subterranean formation, and then injecting the micellar dispersion into the formation.
