Abstract
This invention relates to a method where the soak time, required for solvent and crude oil mixing in the gravity assisted solvent flooding process, is significantly reduced. This is accomplished by inducing vertical flow of solvent into the heavy crude oil part of the reservoir through the use of intermediate wells drilled between injection and production wells and completed in the top of the oil reservoir. Steam or gas may be used prior to the introduction of the solvent to reduce the resistance to subsequent solvent flow.
