Abstract

An actuation system, including a first member having a first profile engagable with a tool operatively arranged for actuating the member from an initial configuration to an actuated configuration. A second member is included that is movable relative to the first member. The second member has a lockout feature configured to prevent engagement of the first member with the tool while the second member is located proximate to the first member. A method of selectively actuating a system is also included.

First claim

What is claimed is:

1. An actuation system for use in a downhole tool, comprising:
a downhole housing comprising a first member and a second member,
the first member having a first profile shape responsive selectively to a tool having a negative of the first profile shape, the tool operatively arranged for actuating the first member from an initial configuration to an actuated configuration; and
the second member movable relative to the first member, the second member having a lockout feature configured to prevent engagement of the first profile with the tool while the second member is located proximate to the first member.

2. The system of claim 1 , wherein the second member has a second profile engagable with the tool or another tool for enabling the second member to be moved away from first member.

3. The system of claim 1 , wherein the lockout feature includes a radial protrusion operatively arranged to prevent engagement of the first profile with one or more fingers of a tool run through the system.

4. The system of claim 1 , wherein the second member is initially held proximate to the first member by a release member.

5. The system of claim 4 , wherein the release member is a shear screw.

6. The system of claim 1 , further comprising a locking mechanism for holding the second member in a position away from the first member.

7. The system of claim 6 , wherein the locking mechanism is a lock ring.

8. The system of 6 , wherein the locking mechanism forms a ratchet engagement with the second member.

9. The system of claim 1 , wherein the first and second members are sleeves.

10. The system of claim 1 , wherein movement of the first member to the actuated configuration opens one or more ports.

11. The system of claim 1 , wherein the first member includes a second profile for enabling the first member to be moved by the tool from the actuated configuration to the initial configuration.

12. The system of claim 1 , wherein the second member has a second profile operatively enagagable with the tool for enabling the tool to move the second member away from the first member.

13. A method of selectively actuating a system in a downhole tool, the system having a downhole housing comprising a first member and a second member, the first member having a profile that is engagable with a tool having a negative shape of the profile operatively arranged for actuating the first member from an initial configuration to an actuated configuration, the method comprising:
positioning a lockout feature of the second member proximate to the profile of the first member; and
preventing engagement between the first member and the tool with the lockout feature.

14. The method of claim 13 , further comprising moving the second member away from the first member for enabling engagement between the first member and the tool.

15. The method of claim 14 , wherein the second member includes a second profile that is engagable with the tool for moving the second member.

16. The method of claim 15 , further comprising actuating the first member from the initial configuration to the actuated configuration.

17. The method of claim 15 , wherein actuating the first member from the initial configuration to the actuated configuration includes opening one or more ports.

18. The method of claim 14 , further comprising holding the second member in a position away from the first member with a locking mechanism after moving the second member away from the first member.

19. The method of claim 18 , wherein holding the second member in the position away from the first member includes forming a ratchet engagement with the second member.

20. The method of claim 14 , wherein the first member is repeatedly transitioned by the tool between the initial configuration and the actuated configuration after moving the second member away from the first member.
