Abstract
A method of producing fluids from a reservoir includes isolating a vertical section of a wellbore from a horizontal section; isolating a production tubing from the reservoir; pumping fluid from the reservoir adjacent a toe segment into a production tubing toe segment and towards the heel segment; and pumping fluid from the reservoir adjacent a heel segment into the production tubing heel segment and towards the vertical section, and pumping fluid up the vertical section to the surface.
Claims8
A method of producing fluids from a reservoir using a wellbore having a vertical section comprising a casing defining an annulus, and a horizontal section comprising at least a heel segment and a toe segment, and production tubing having a vertical length and a horizontal length comprising a heel segment and a toe segment, wherein the vertical section of the wellbore is isolated from the horizontal section, the method comprising:
- (a) isolating the production tubing from the reservoir, such that reservoir fluids cannot enter the production tubing except through a pump;
- (b) pumping fluid from the reservoir adjacent the toe segment into the production tubing toe segment and towards the heel segment;
- and
- (c) pumping fluid from the reservoir adjacent the heel segment into the production tubing heel segment and towards the vertical section;
- and
- (d) pumping fluid in the vertical section to the surface.
