Method of flowing viscous hydrocarbons in a single well injection/production system
Patent
·
OSTI ID:7283546
This patent describes a method for enhancing the flow of viscous hydrocarbons from a subterranean formation wherein the formation is transversed by a cased wellbore having a first tubing string, a first packer and a second tubing string, a second packer combination therein. This patent describes improvement in opening a tubing access means operably connected to the second string; simultaneously flowing a portion of the drive fluid through the tubing access means and into the wellbore; the drive fluid externally heating the first tubing string and the produced fluids therein; exhausting the portion of the drive fluid within the wellbore at the surface.
