A system and process is disclosed for retorting oil shale and extracting shale oil and other hydrocarbons therefrom, in which a cased heat delivery well is drilled generally vertically through an overburden and then through a body of oil shale to be retorted to the bottom thereof, generally horizontally under the body of oil shale to be retorted, and then back to the earth surface. Heat energy is transmitted conductively to the body of oil shale to be retorted from a closed loop heat delivery module in the well, the module comprising a fluid transmission pipe containing a heating fluid heated to at least a retorting temperature. Heat energy is also transmitted to the body of oil shale to be retorted above the fluid transmission pipe by vapor conduits that conduct retort vapors upward through the body of oil shale to be retorted; the ascending retort vapors condense and reflux, delivering their latent heat of vaporization to the body of oil shale to be retorted, and the condensed retort liquids descend. If not recycled, the retort liquids are collected in a sump at the bottom of a production well and are transmitted to the surface for processing. The vapor conduits communicate at upper ends thereof with the production well, so that vapors that do not reflux are collected in the production well and are transmitted to the surface for processing.

A retortable container and an easy-opening closure for hermetic sealing of an open end thereof. The closure includes a metal end ring adapted to be double seamed to an open end of the retortable container, an intermediate area extending radially inward and defining an opening to an interior of the container, and a folded area folded into the interior of the container. The folded area extends radially outward from the opening and substantially parallel to at least an adjacent portion of the intermediate area. A first membrane patch overlaps and is bonded to an under side of the intermediate area of the end ring such that the first membrane patch prevents contamination of contents of the container by the metal end. A second membrane patch covers the opening and is bonded to an upper side of the first membrane patch. The bonds have predetermined shear and tensile force strengths sufficient to withstand shear and tensile forces created during retort processing of the container, while allowing easy-opening of the container by peeling the second membrane patch.
