Abstract
A method for the solvent stimulation of a well producing heavy oil containing large fractions of free water by injecting a solvent into the producing well, having a density and viscosity substantially less than the viscous formation oil and a viscosity equal to or slightly greater than water at formation conditions, shutting-in the producing well to allow a soak period, and returning the well to production with substantially less water production than prior to stimulation.
