Abstract
A method is provided for increasing the rate of injection of flooding fluids into injection wells. A slug of polar solvent or a mixture of polar solvent and non-aqueous flooding fluid is injected into the injection well to displace aqueous and hydrocarbon liquids in the rock surrounding the injection well. Thereafter, the solvent is removed from the vicinity of the injection well by flooding fluid. The process may be repeated following each time water is injected into the injection well.
