Abstract

A method for the in-situ recovery of viscous petroleum hydrocarbons from an underground formation includes the following. A production well is provided within the formation. Solvents are maintained in the formation above the production well which are capable of dissolving in and diluting the hydrocarbons to promote drainage of the solvent-diluted hydrocarbon toward the production well. A vapour chamber is created above the production well in the hydrocarbon-depleted formations resulting from said drainage. A hot zone is maintained adjacent the production well to vaporize the solvents contained in the downwardly draining hydrocarbons prior to their entry into the production well. These vaporized solvents move upwardly through the vapour chamber in a continuing manner to again contact said hydrocarbons in the formations at the boundaries of the vapour chamber to promote the continued dilution and drainage of the hydrocarbons toward said production well whereby a substantial portion of the solvents are recycled in a closed-loop fashion. Special concentric tubing closed loop heating systems provide the desired hot zones to enhance the operation of the process as required.
