Abstract

A well completion has an inner completion with a control valve surrounded by spaced seals that is positioned in an outer completion, such as a sand control completion. A control line extends from the valve through one of the seals. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Claims

a completion positioned inside the sand control device having a first seal assembly sealingly mating with the first inner polished bore receptacle and having a second seal assembly sealingly mating with the second inner polished bore receptacle;

a valve of the completion positioned between the first and second seal assemblies; and

a control line extending from the valve and through the first seal assembly.

2. The system of claim 1, wherein the sand control device is a sand screen.

3. The system of claim 1, wherein the sand control device is a slotted liner.

4. The system of claim 1, further comprising an intelligent completions device in the completion.

5. The system of claim 1, wherein the control line is a fiber optic line and the fiber optic line that provides functionality.

6. The system of claim 1, wherein:

the first polished bore receptacle has a control line passageway therethrough; and

the control line extends through the control line passageway.

7. The system of claim 1, further comprising:

the first polished bore receptacle has a primary production passageway that is eccentric with respect to a centerline of the first polished bore receptacle.

8. The system of claim 1, further comprising a locator device.

9. The system of claim 1, further comprising:

a second sand control device;

the second first polished bore receptacle is positioned between the sand control device and the second control device.

10. The system of claim 9, further comprising:

a third polished bore receptacle positioned below the second sand control device;

the completion having a third seal assembly sealingly mating with the third inner polished bore receptacle.

11. The system of claim 9, further comprising:

a fourth polished bore receptacle positioned between the sand control device and the second sand control device; and

the completion having a fourth seal assembly sealingly mating with the fourth inner polished bore receptacle.

12. The system of claim 9, further comprising:

a second valve of the completion positioned below the second seal assembly; and

a control line extending from the valve and through the first seal assembly and the second seal assembly.

13. The system of claim 9, wherein the second sand control device is a sand screen.

14. The system of claim 9, wherein the second sand control device is a slotted liner.

15. The system of claim 1, further comprising:

a circulating valve;

one of the first polished bore receptacle and the second polished bore receptacle is positioned between the circulating valve and the sand control device.

16. The system of claim 1, further comprising a gravel pack.

17. A method for completing a well, comprising:

completing a well so as to define an area of fluid ingress into a completion;

positioning a conduit within the completion;

sealing between the conduit and the completion above and below the area of fluid ingress with spaced seals;

controlling the flow into the conduit with a valve; and

routing a control line from the valve through one of the seals.

18. The method of claim 17, further comprising providing a screen at the area of fluid ingress.

19. The method of claim 17, further comprising gravel packing the well.

20. The method of claim 17, further comprising:

completing the well to define a plurality of areas of fluid ingress;

isolating the areas of fluid ingress from one another by sealing between the conduit and the completion above and below the areas of fluid ingress with spaced seals;

independently controlling the flow into the conduit from each of the areas of fluid ingress.

21. The method of claim 17, wherein the sealing comprises inserting a seal assembly attached to the conduit into a mating polished bore receptacle of the completion.

22. The method of claim 17, further comprising measuring a parameter between the spaced seals.

23. The method of claim 17, further comprising engaging a locator device and ensuring proper alignment between the completion and the conduit.

24. The method of claim 17, further comprising isolating a circulating valve of the completion with one of the spaced seals.

25. A system for controlling flow in a well having a sand control completion therein, comprising:

an inner completion comprising a tubing, a first seal, a second seal, and a valve between the first seal and the second seal;

the first seal positioned and adapted to seal above a sand screen of the sand control completion;

the second seal positioned and adapted to seal below the sand screen;

a control line extending from the valve and through the first seal.

26. The system of claim 25, further comprising an intelligent completions device of the inner completion.

27. The system of claim 25, wherein:

the first seal has a control line passageway therethrough; and

the control line extends through the control line passageway.

28. The system of claim 25, further comprising:

the second seal is positioned to seal between two sand screens of the sand control completion.

29. The system of claim 28, further comprising:

a third seal of the inner completion is positioned and adapted to seal below a second sand screen of the sand control completion.

30. The system of claim 28, further comprising a fourth seal of the inner completion positioned and adapted to seal between the two sand screens.

31. The system of claim 28, further comprising a second valve of the inner completion positioned below the second seal.

32. The system of claim 25, further comprising:

one of the first seal and the second seal is positioned to seal between a circulating valve of the sand control completion and the screen.

33. A method of controlling flow in a well having a sand control completion therein, comprising:

running an inner completion into the sand control completion;

sealing between the inner completion and the sand control completion above a sand screen of the sand control completion to create an isolation zone;

controlling a valve of the inner completion to selectively control the flow into the inner completion, the valve positioned in the isolation zone.

34. The method of claim 33, further comprising running a control line from the valve through a seal used to seal between the inner completion and the sand control completion.
