Abstract (en)
[origin: GB2507506A] A method of pumping a hydrocarbon fluid from a wellbore includes deploying a tubing string 7 and a first pump system 15, in fluid communication with the tubing string 7, within a wellbore. The first pump system 15 is employed to generate a production fluid 3 by heating the hydrocarbon fluid as it is pumped into the tubing string 7 so as to form a counter current heat exchanger between the production fluid 3 within the tubing string and the hydrocarbon fluid 36 located within the wellbore. The method finds particular application within horizontal, high angle or vertical wells in heavy or extra heavy oil fields.
