Abstract
A method of initiating or accelerating the establishment of fluid communication between injection and production wells located in a formation, including injecting sufficient solvent into the wellbores of the wells such that the solvent occupies more than the horizontal sections of the wells; pressurizing the solvent column in the injection wellbore and optionally also the solvent column in the production wellbore by injecting gas such that the pressures at the toe and heel of the horizontal section of the injection well and optionally the production well are greater than a fracture pressure of the formation; maintaining the pressure in the injection wellbore and optionally also the production wellbore; depressurizing the injection wellbore and optionally the production wellbore, either simultaneously or consecutively in the case where both wellbores have been pressurized; and repeating the pressurization and depressurization steps for at least one more cycle to generate pressure swings.
