A method and apparatus for construction of a subsurface barrier for the recovery of petroleum fluids from the subsurface by steam and/or solvent injection. Multiple propped vertical inclusions at various azimuths and depths are constructed from multiple wells so that the inclusions intersect and coalesce. The inclusions are made impermeable by a variety of means including the proppant swelling to fill the voids of the inclusions. The proppant includes ceramic beads coated with an electrically conductive and heat hardenable resin. The resin is electrically heated and flows to fill the voids in the inclusions as the resin hardens. The proppant includes sand or ceramic beads that are subject to cold saline water circulated between the wells to freeze the formation pore water. The proppant includes low viscosity grout that is injected with a time delay setting agent or electrically conductive grout that is heated and set by electric current passing through the grout. |
