Abstract

A system (100, 200, 300, 400, 500) for producing fluids from a subterranean zone (110) comprises a tubing string (112) disposed in a well bore (114), the tubing string (112) adapted to communicate fluids from the subterranean zone (110) to a ground surface (116). A downhole fluid lift system (118, 418, 518) is operable to lift fluids towards the ground surface (116). A downhole fluid heater (120) is disposed in the well bore (114) and is operable to vaporize a liquid in the well bore (114). A seal (122) between the downhole fluid lift system (118, 418, 518) and the downhole fluid heater (120) is operable to isolate a portion of the well bore (114) containing the downhole fluid lift system (118, 418, 518) from a portion of the well bore (114) containing the downhole fluid heater (120). A method comprises: disposing a tubing string (112) in a well bore (114); generating vapor in the well bore (114); and lifting fluids from the subterranean zone (110) to a ground surface (116) through the tubing string (112).

Claims (22)

1. A system for producing fluids from a subterranean zone, comprising:

a downhole fluid lift system adapted to be at least partially disposed in the well bore, the downhole fluid lift system operable to lift fluids towards a ground surface;

a downhole fluid heater adapted to be disposed in the well bore, the downhole fluid heater operable to heat a liquid in the well bore; and a seal between the downhole fluid lift system and the downhole fluid heater, the seal operable to selectively seal with the well bore and isolate a portion of the well bore containing the downhole fluid lift system from a portion of the well bore containing the downhole fluid heater.
2. The system of claim 1, wherein the downhole fluid lift system comprises gas lift system.
3. The system of claim 1, wherein the downhole fluid lift system comprises at least one of an electric submersible pump or a progressive cavity pump.
4. The system of claim 1, wherein the downhole fluid lift system is adapted to circulate fluids in the portion of the well bore containing the downhole fluid lift system while isolated from the portion of the well bore containing the downhole fluid heater.
5. The system of claim 1, further comprising a surface pump adapted to circulate fluids in the portion of the well bore containing the downhole fluid lift system while isolated from the portion of the well bore containing the down.hole fluid heater.
6. The system of claim 1, wherein the downhole fluid heater comprises a steam generator.

8. The system of claim 7, further comprising a tubing string disposed in a well bore, the tubing string adapted to communicate fluids from the subterranean zone to a ground surface.
9. The system of claim 7, further comprising a seal between the pump inlet and the downhole fluid heater such that fluid flow between a portion of the well bore containing the pump inlet and a portion of the well bore containing the downhole fluid heater is limited by the seal.
10. The system of claim 7, wherein the pump comprises an electric submersible pump.
11. The system of claim 7, wherein the pump is adapted to circulate fluids.
12. The system of claim 7, further comprising a surface pump.
13. The system of claim 7, wherein the downhole fluid heater comprises a steam generator.
14. A method, comprising:

with an artificial lift system in a well bore, introducing heated fluid into a subterranean zone from the well bore; and artificially lifting fluids from the subterranean zone to a ground surface using the artificial lift system.
15. The method of claim 14, further comprising isolating a portion of the well bore containing the artificial lift system from a portion where the heated fluid is being introduced into the subterranean zone.
16. The method of claim 15, further comprising circulating fluid in the portion of the well bore containing the artificial lift system while introducing heated fluid into the subterranean zone.
17. The method of claim 16, wherein circulating fluid comprises circulating fluid using the artificial lift system.
18. The method of claim 16, wherein circulating fluid comprises circulating fluid using a surface pump.
19. The method of claim 15, further comprising cooling a downhole pump present in the well bore while vapor is being generated.
20. The method of claim 14, further comprising heating the fluid in the well bore.
21. A method, comprising:
artificially lifting fluids from a subterranean zone through a well bore while a downhole heated fluid generator resides in the well bore.
22. The method of claim 21 wherein the downhole heated fluid generator is a steam generator.
