Abstract: A steam assisted gravity drain for heavy oil, comprising a body sub-assembly having first and second ends; a top sub insertable into the body sub-assembly; a bottom sub insertable into the body sub-assembly; first and second diffuser caps encircling the top sub and the bottom sub, respectively; a plurality of radially arranged flow tubes extending between the diffuser caps and the body sub-assembly; and a sliding sleeve extending between the top and bottom subs. A method of flow conditioning for heavy oil pipelines, comprising the steps of attaching a plurality of steam assisted gravity drains in a closed position to a liner; running the drains vertically downhole into the horizontal leg of a well; and running a shifting tool downhole and selectively opening the sleeve of the drain by stabbing the shifting tool into the sleeve and pulling the sleeve back.

Abstract: An assembly and method for downhole equipment deployment comprising a liner hanger attachable to deployable equipment, a top sub insertable into the liner hanger and attachable to a tubing string, a lock piston releasably connectable to the top sub, and lock pins insertable through the top sub, the liner hanger, and the lock piston, the liner hanger and associated equipment remotely releasable from the top sub and the lock piston.
