摘要： A method for stimulating heavy oil recovery from CHOPS wells at or nearing the end of productive life but not experiencing water-out, wherein produced water is heated to below boiling point and injected back downhole to reduce heavy oil viscosity in the near-wellbore region and surrounding the wormhole network, enabling existing reservoir pressure to drive the reduced-viscosity heavy oil toward the well for production to surface. The injection-soak-production cycle can be repeated as desired so long as adequate reservoir pressure exists.

摘要： Systems and methods for cooling process equipment are provided. The system includes a process fluid source, and a heat exchanger fluidly coupled with the process equipment and the process fluid source. The heat exchanger is configured to receive a process fluid from the process fluid source and transfer heat from the process equipment to the process fluid. The system also includes a control system fluidly coupled with the heat exchanger. The control system is configured to vary a temperature of the process fluid heated in the heat exchanger. Further, at least a portion of the process fluid heated in the heat exchanger is delivered into a wellbore at a temperature below a boiling point of the process fluid.

摘要： 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).

摘要： A method of pumping a hydrocarbon fluid from a wellbore (4) and a hydrocarbon completion (1) implementing the methodology is described. The method comprises deploying a tubing string (7) and a first pump system (15), in fluid communication with the tubing string, within a wellbore. The first pump system is employed to generate a production fluid (17) by heating the hydrocarbon fluid as it is pumped into the tubing string so as to form a counter current heat exchanger between the production fluid within the tubing string and the hydrocarbon fluid located within the wellbore. The counter current heat exchanger provides a means for preheating the hydrocarbon fluid before it reaches the first pump system. As a result the viscosity of the hydrocarbon fluid is reduced thus making it easier to pump to the surface. The method finds particular application within horizontal, high angle or vertical wells in heavy or extra heavy oil fields.
