Abstract
Superheated steam from a generator (10) proximate a well (14) is delivered through an output pipe (12) that communicates through a dual entry wellhead (17) with downhole steam piping (18) extending into the well (14). Steam is delivered at approximately 50 PSIG over the frictional and other losses encountered from the surface to the steam piping outlet (19). Oil is extracted through production tubing (20) passing through wellhead (17). Production tubing (20) and steam delivery piping (18) are secured in parallel relationship by clamps (46). The production tubing (20) communicates with a lift pump, and the steam piping (18) is terminated generally at a midpoint of the production tubing (20), several feet above the lift pump. A thermocouple (43) is placed approximately two feet below the end of the steam piping (18).
