Abstract

An isolation system is disclosed that contains a lower wet connect portion; a central production tubing; an isolation device associated with the central production tubing, and at least one control line. Further at least one control line is associated with the lower wet connect portion and is disposed through an inside diameter of the isolation device. Further method for isolating a lower completion is disclosed that includes conveying an isolation assembly to the lower completion, the isolation assembly including a lower wet connect portion, at least one control line, a central production tubing, and an isolation device, and routing the at least one control line through an inside diameter of the isolation device. Further completion system is disclosed that contains a lower completion system and an isolation system associated with the lower completion system.

First claim

The invention claimed is:

1. An isolation system comprising:
a lower wet connect portion;
a central production tubing;
a fluid crossover associated with the central production tubing;
an isolation device associated with the central production tubing; and
a control line, wherein the control line is associated with the lower wet connect portion and is disposed through the isolation device, wherein the control line crosses over from within the central production tubing to be along the central production tubing.

2. The isolation system of claim 1 , wherein the control line is disposed through an inside diameter of the isolation device.

3. The isolation device of claim 1 , wherein the control line is disposed through a drilled hole of the isolation device.

4. The isolation system of claim 1 , wherein the control line includes a hydraulic line.

5. The isolation system of claim 1 , wherein the control line includes a fiber optic line.

6. The isolation system of claim 1 , wherein the control line includes an electrical cable.

7. The isolation system of claim 1 , wherein the control line includes an injection conduit.

8. The isolation system of claim 7 , wherein the injection conduit is a chemical injection conduit.

9. The isolation system of claim 1 , further comprising a concentric valve associated with the central production tubing.

10. The isolation system of claim 9 , wherein the concentric valve is operatively coupled the control line.

11. The isolation system of claim 9 , wherein the concentric valve controls flow into the central production tubing.

12. A method for isolating a lower completion, the method comprising:
conveying an isolation assembly to the lower completion, the isolation assembly including a lower wet connect portion, a control line, a central production tubing, an isolation device, and a fluid crossover associated with the central production tubing; and
routing the control line through the isolation device, wherein the control line crosses over from within the central production tubing to be along the central production tubing.

13. The method of claim 12 , further comprising routing the control line through an inside diameter of the isolation device.

14. The method of claim 12 , further comprising:
drilling a hole through the isolation device; and
routing the control line through the drilled hole of the isolation device.

15. The method of claim 12 , wherein the control line includes a hydraulic line.

16. The method of claim 12 , wherein the control line includes a fiber optic line.

17. The method of claim 12 , wherein the control line includes an electrical cable.

18. The method of claim 12 , wherein the control line includes an injection conduit.

19. The method of claim 12 , further comprising:
selectively providing a flow to the central production tubing via a concentric valve; and
selectively engaging the concentric valve via the control line.

20. A completion system comprising:
a lower completion system; and
an isolation system associated with the lower completion system including:
a lower wet connect portion;
a central production tubing;
a fluid crossover associated with the central production tubing;
an isolation device associated with the central production tubing;
a concentric valve associated with the central production tubing; and
a control line associated with the concentric valve, wherein the control line is associated with the lower wet connect portion and the lower completion system and is disposed through the isolation device, wherein the control line crosses over from within the central production tubing to be along the central production tubing.
