Abstract

A tubular valve system includes, a tubular, a primary valve actuatable to control occlusion of at least one port fluidically connecting an inner bore of the tubular with an outside of the tubular, and a contingency valve actuatable to control occlusion of at least one port fluidically connecting the inner bore with the outside of the tubular.

Claims

1. A tubular valve system, comprising:

a tubular;

a primary valve actuatable to control occlusion of at least one port fluidically connecting an inner bore of the tubular with an outside of the tubular; and

a contingency valve actuatable to control occlusion of at least one port fluidically connecting the inner bore with the outside of the tubular.

2. The tubular valve system of claim 1, wherein the primary valve is actively controlled and the contingency valve is passively controlled.

3. The tubular valve system of claim 1, wherein the tubular valve system is deployable within a wellbore.

4. The tubular valve system of claim 1, wherein the primary valve is controlled by one of electrical power and hydraulic pressure.

5. The tubular valve system of claim 1, wherein the contingency valve is controlled by mechanical actuation.

6. The tubular valve system of claim 1, wherein the contingency valve includes a sleeve that is movable relative to the tubular.

7. The tubular valve system of claim 6, wherein the sleeve has at least one contingency opening that can be aligned with the at least one port to open the at least one port or misaligned with the at least one port to occlude the at least one port.

8. The tubular valve system of claim 6, wherein the sleeve is slidably sealingly engaged with the tubular.

9. The tubular valve system of claim 6, further comprising a collet in operable communication with the sleeve and the tubular to maintain the sleeve in a position relative to the tubular when the sleeve is not being moved.

10. The tubular valve system of claim 6, wherein the sleeve includes a profile engagable with a shifting tool.

11. The tubular valve system of claim 1, further comprising a collar having at least one primary opening positionable at least between a first position aligning the primary opening with the at least one port and a second position misaligning the primary opening with the at least one port to occlude the at least one port.

12. The tubular valve system of claim 11, wherein the collar is movable from the first position to the second position by actuation of the contingency valve.

13. The tubular valve system of claim 1, further comprising a collar valve configured to defeat the primary valve upon actuation thereof.

14. The tubular valve system of claim 1, wherein the primary valve is configured to control occlusion of at least one first port and the contingency valve is configured to control occlusion of at least one second port and the at least one first port is not the at least one second port.

15. A method of valving a tubular, comprising:

actively actuating a primary valve disposed at the tubular; and

maintaining a contingency valve disposed at the tubular in reserve.

16. The method of valving a tubular of claim 15, further comprising actuating the contingency valve upon loss of performance of the primary valve.

17. The method of valving a tubular of claim 16, wherein the actuating the contingency valve is via mechanical actuation.

18. The method of valving a tubular of claim 15, further comprising engaging the contingency valve with a shifting tool.

19. The method of valving a tubular of claim 15, further comprising moving a sleeve relative to the tubular.

20. The method of valving a tubular of claim 19, further comprising moving a collar relative to the tubular.

21. The method of valving a tubular of claim 15, further comprising actuating the contingency valve to open the contingency valve.

22. The method of valving a tubular of claim 21, wherein the actuating the contingency valve includes closing the primary valve.

23. The method of valving a tubular of claim 21, further comprising defeating the primary valve with the actuating of the contingency valve.
