Abstract

A multi-zone single trip open hole completion system includes an outer tubular assembly including an uphole end, a downhole end, an inner tubular assembly, an anchor arranged on the outer tubular assembly, and an anchor setting assembly provided on one of the outer tubular assembly and the inner tubular assembly. The anchor setting assembly is operable to selectively set the anchor. An isolation flow path is in the outer tubular. A flow control system is arranged on the inner tubular assembly. The flow control system selectively blocks flow through the inner tubular assembly. A remotely operated valve is arranged in one of the inner tubular assembly and the outer tubular assembly. The remotely operated valve is operable to close fluid flow through the tubular. An isolation packer is arranged along the outer tubular assembly. Closing the remotely operated valve enables the anchor, and the isolation packer to be set.

First claim

What is claimed is:

1. A multi-zone single trip open hole completion system comprising:
an outer tubular assembly including an uphole end, a downhole end, and an intermediate portion;
an inner tubular assembly;
an anchor arranged on the outer tubular assembly;
an anchor setting assembly provided on one of the outer tubular assembly and the inner tubular assembly, the anchor setting assembly being operable to selectively set the anchor;
an isolation flow path in the outer tubular;
a flow control system arranged on the inner tubular assembly, the flow control system selectively blocking flow through the inner tubular assembly;
a remotely operated valve arranged in one of the inner tubular assembly and the outer tubular assembly, the remotely operated valve being operable to close fluid flow through the outer tubular assembly; and
an isolation packer arranged along the intermediate portion of the outer tubular assembly, wherein closing the remotely operated valve enables pressure to be applied to the outer tubular assembly to set the anchor, and the isolation packer.

2. A multi-zone single trip open hole completion system comprising:
a tubular assembly including an uphole end, a downhole end, and an intermediate portion;
an anchor arranged on the tubular assembly;
a remotely operated valve arranged in the tubular assembly, the remotely operated valve being operable to close the downhole end of the tubular assembly to fluid flow; and
an isolation packer arranged along the intermediate portion, wherein closing the remotely operated valve enables pressure to be applied to the outer tubular assembly to set the anchor and the isolation packer.

3. The multi-zone single trip open hole completion system according to claim 2 , further comprising: an isolation flow path including an isolation valve arranged in the tubular assembly.

4. The multi-zone single trip open hole completion system according to claim 2 , wherein the anchor is a non-sealing anchor that does not form a seal with a surface of the wellbore.

5. The multi-zone single trip open hole completion system according to claim 2 , further comprising: an anchor setting assembly arranged in the tubular at the anchor.

6. The multi-zone single trip open hole completions system according to claim 5 , wherein, the flow control system includes an object seat and a selectively activatable bypass flow path.

7. A multi-zone single trip open hole completion system comprising:
an inner tubular assembly;
an outer tubular assembly;
an anchor arranged on the outer tubular;
an anchor setting assembly operable to selectively activate the anchor;
an isolation flow path in the outer tubular assembly;
a flow control system arranged on the inner tubular assembly, the flow control system including a flow control device that selectively blocks flow through the inner tubular assembly; and
an isolation packer arranged along the outer tubular, wherein the flow control system includes a bypass flow path that enables fluid to bypass the flow control device to set the isolation packer.

8. The multi-zone single trip open hole completion system according to claim 7 , wherein the anchor is a non-sealing anchor that does not form a seal with a surface of the wellbore.

9. The multi-zone single trip open hole completion system according to claim 7 , further comprising: an isolation valve arranged above the downhole end of the tubular.

10. The multi-zone single trip open hole completion system according to claim 7 , wherein the flow control system includes an object seat.

11. The multi-zone single trip open hole completion system according to claim 10 , wherein the flow control system forms part of the anchor setting assembly and the object seat includes an object capture member.

12. A method of forming a multi-zone single trip open hole completion comprising:
running a multi-zone single trip open hole completion assembly including an anchor and an isolation packer into an open hole well bore to a selected depth;
flowing fluid through a bottom hole assembly (BZA) of the completion assembly during run in;
closing a remotely operated valve arranged in the BZA to stop the flow of fluid; and
setting the anchor and the isolation packer by applying pressure to the completion assembly.

13. The method of claim 12 , further comprising:
detecting that the remotely operated valve did not function; and
setting the anchor with a flow control system that blocks flow through an inner tubular assembly.

14. The method of claim 13 , further comprising: opening a bypass flow path to bypass the flow control system.

15. The method of claim 14 , further comprising: closing an isolation flow path in the completion assembly.

16. The method of claim 15 , further comprising: flowing additional fluid through the bypass flow path to set the isolation packer.

17. The method of claim 12 , wherein when setting the anchor occurs before production zones in the open hole well bore are isolated one from another.

18. The method of claim 12 , wherein setting the anchor includes engaging the anchor with surface of a casing tubular.

19. The method of claim 18 , wherein setting the isolation packer includes setting a plurality of isolation packers.

20. The method of claim 19 , wherein setting the plurality of isolation packers includes setting at least one of the plurality of isolation packers against the casing tubular and another of the plurality of isolation packers against a surface of the open hole well bore.

21. The method of claim 12 , wherein setting the isolation packer includes setting a plurality of isolation packers as a group.

22. A method of forming a multi-zone single trip open hole completion comprising:
running a multi-zone single trip open hole completion assembly including an anchor and an isolation packer into an open hole well bore to a selected depth;
flowing fluid through a bottom zone assembly (BZA) of the completion assembly during run in;
setting the anchor by operating a flow control system to increase pressure at with an anchor setting assembly operable to set the anchor;
blocking the fluid flowing through the BZA; and
setting the isolation packer by applying pressure to the completion assembly.

23. The method of claim 22 , wherein operating the flow control system includes dropping an object onto an object seat.

24. The method of claim 22 , wherein setting the isolation packer includes bypassing the flow control system.

25. The method of claim 22 , wherein blocking the fluid flow includes picking up a closing tool to close an isolation valve.
