Abstract

A SAGD system including at least one borehole having a tubular therein; and at least one baffle disposed on the tubular, the baffle extending radially outwardly of the tubular into proximity with a formation.

Claims

1. A SAGD system comprising:

at least one borehole having a tubular therein; and

at least one baffle disposed on the tubular, the baffle extending radially outwardly of the tubular into proximity with a formation.

2. A SAGD system as claimed in claim 1 wherein the at least one baffle is configured to withstand a heated fluid.

3. A SAGD system as claimed in claim 2 wherein the heated fluid is steam.

4. A SAGD system as claimed in claim 1 wherein the system further includes a plurality of open hole anchors.

5. A SAGD system as claimed in claim 4 wherein the anchors are spaced along a length of the tubular.

6. A downhole configuration for a SAGD system comprising:

a tubular; and

one or more baffles on the tubular, the one or more baffles configured to be extendible in a radial direction from the tubular to reduce annular flow along the tubular when installed in a borehole.

7. A downhole configuration for a SAGD system as claimed in claim 6 wherein the radial direction is radially outwardly from the tubular.

8. A downhole configuration for a SAGD system as claimed in claim 6 wherein the one or more baffles are configured to extend radially into proximity with a borehole within which the tubular is intended to be installed.

9. A downhole configuration for a SAGD system as claimed in claim 6 wherein the one or more baffles are constructed of a heat tolerant material.

10. A downhole configuration for a SAGD system as claimed in claim 9 wherein the heat tolerant material is metal.

11. A downhole configuration for a SAGD system as claimed in claim 6 wherein the one or more baffles are metal deformable seals.

12. A downhole configuration for a SAGD system as claimed in claim 6 wherein the one or more baffles come into contact with a formation defining the borehole.

13. A downhole configuration for a SAGD system as claimed in claim 6 wherein the one or more baffles form a seal with a formation defining the borehole.

14. A borehole system comprising:

a borehole; and

one or more metal-to-formation baffles extending radially to proximity with a formation interface.

15. A borehole system as claimed in claim 14 wherein the one or more metal-to-formation baffles are positioned relative to the borehole to contain a fluid to a target area.

16. A borehole system as claimed in claim 15 wherein the fluid is heated.

17. A borehole system as claimed in claim 14 wherein the one or more metal to formation baffles are configured and positioned to tailor a production profile of the wellbore system.

18. A borehole system comprising:

a tubular configured to be disposed within an open hole borehole, the tubular being intended to be exposed to a heated fluid; and

one or more tubular-to-formation baffles spaced along the tubular and extending into proximity with the formation.

19. A borehole system as claimed in claim 18 wherein one or more of the one more tubular-to-formation baffles comprise metal material.

20. A borehole system as claimed in claim 18 wherein one or more of the one more tubular-to-formation baffles comprise polymeric material.
