Abstract
A method of recovering oil from a hydrocarbon-bearing subterranean geologic formation includes producing a first hydrocarbon composition and injecting a first injection fluid including a first viscoelastic polymer and a first brine solution. The first viscoelastic polymer has a shear viscosity from 500 to 700 cP at a shear rate of 0.5 to 2 s. A second hydrocarbon composition is produced and a second injection fluid including a viscous polymer and a second brine solution is injected. The viscous polymer has a shear viscosity greater than the first viscoelastic polymer. Further, a third hydrocarbon composition is produced and a third injection fluid including a second viscoelastic polymer and a third brine solution is injected. The second viscoelastic polymer has a shear viscosity less than the viscous polymer. The method further includes producing a fourth hydrocarbon composition.
