ABSTRACT:
A process for recovering petroleum from relatively impermeable formations. A permeable structure is formed to extend radially outward from the well bore and vapor, including solvent vapor, is introduced in a manner to condense primarily adjacent petroleum-containing portions of the formation, thereby forming a mixture of solvent and petroleum sufficiently mobile to flow downwardly and inwardly to a lower portion of the well bore leaving in place a leached volume of solids from which most of the petroleum has been removed.
