Abstract

A bottomhole assembly for deployment within a wellbore is disclosed. The wellbore string includes a port and a flow control member, wherein the latter is displaceable to open and close the port. The flow control member comprises a first mandrel; a second mandrel including a locator for disposition within a locate profile of the wellbore string to resist displacement of the second mandrel, relative to the locate profile, and locating the bottomhole assembly within the wellbore string. A shifting tool is disclosed, the shifting tool including two gripper surfaces; and two shifting tool actuators, translatable with the first mandrel. The shifting tool actuators displace the shifting tool by displacing the first mandrel downhole or uphole relative to the second mandrel; and the second mandrel includes a retainer for limiting displacement of the shifting tool, relative to second mandrel, in both of downhole and uphole directions.

First claim

The invention claimed is:

1. A bottomhole assembly for deployment within a wellbore string disposed within a wellbore, the wellbore string including a port and a flow control member, wherein the flow control member is displaceable relative to the port for effecting opening and closing of the port, comprising:
a first mandrel;
a second mandrel including a locator for becoming disposed within a locate profile of the wellbore string such that resistance to displacement of the second mandrel, relative to the locate profile, is effected, and such that locating of the second mandrel within the wellbore string is thereby effected;
a shifting tool including a first gripper surface and a second gripper surface;
a first shifting tool actuator, translatable with the first mandrel; and
a second shifting tool actuator, translatable with the first mandrel;
wherein the shifting tool is co-operatively disposed relative to the second mandrel such that while the locator is disposed within a locate profile:
displacement of the shifting tool, in response to urging by the first shifting tool actuator that is effected by downhole displacement of the first mandrel relative to the second mandrel, is with effect that the first gripper surface is displaced outwardly to a first gripper surface gripping position for becoming disposed in gripping engagement with the flow control member; and
displacement of the shifting tool, in response to urging by the second shifting tool actuator that is effected by uphole displacement of the first mandrel relative to the second mandrel, is with effect that the second gripper surface is displaced outwardly to a second gripper surface gripping position for becoming disposed in gripping engagement with the flow control member.

2. The bottomhole assembly as claimed in claim 1 ;
wherein:
during the outwardly displacement of the first gripper surface to the first gripper surface gripping position, movement of the first gripper surface includes a rotational movement; and
during the outwardly displacement of the second gripper surface to the first gripper surface gripping position, movement of the second gripper surface includes a rotational movement.

3. The bottomhole assembly as claimed in claim 2 ;
wherein the rotational movement of the second gripper surface during the outwardly displacement of the second gripper surface to the second gripper surface gripping position is counter to the rotational movement of the first gripper surface during the outwardly displacement of the first gripper surface to the first gripper surface gripping position.

4. The bottomhole assembly as claimed in claim 1 ;
wherein the shifting tool includes a rocker.

5. The bottomhole assembly as claimed in claim 4 ;
wherein:
the first gripper surface is disposed closer to one end of the rocker relative to a second opposite end of the rocker; and
the second gripper surface is disposed closer to the second end of the rocker relative to the first end.

6. The bottomhole assembly as claimed in claim 1 ;
wherein:
the downhole displacement of the first mandrel relative to the second mandrel, by which the urging of the first shifting tool actuator, in response to which the shifting tool is displaceable, is effectible, is a longitudinal displacement of the first mandrel along in a first direction; and
the uphole displacement of the first mandrel relative to the second mandrel, by which the urging of the second shifting tool actuator, in response to which the shifting tool is displaceable, is effectible, is a longitudinal displacement of the first mandrel in a second direction, wherein the second direction is opposite, or substantially opposite, to the first direction.

7. The bottomhole assembly as claimed in claim 1 ;
wherein:
the first mandrel includes one of a pin and a j-slot;
the second mandrel includes the other one of the-pin and the j-slot, such that the second mandrel is coupled to the first mandrel via disposition of the pin within the j-slot;
the pin is movable within the j-slot;
engageablity of the first shifting tool actuator with the gripper, for effecting the outwardly displacement of the first gripper surface to the first gripper surface gripping position, is determined based upon positioning of the pin relative to the j-slot; and
engageablity of the second shifting tool actuator with the gripper, for effecting the outwardly displacement of the second gripper surface to the second gripper surface gripping position, is determined based upon positioning of the pin relative to the j-slot.

8. The bottomhole assembly as claimed in claim 1 ;
wherein, for at least one of the first and second gripper surfaces, the second mandrel includes an aperture through which a one of the at least one of the first and second gripper surfaces is displaceable in response to the urging by the respective one of the first and second shifting tools.

9. The bottomhole assembly as claimed in claim 8 ;
wherein the shifting tool is translatable with the second mandrel.

10. The bottomhole assembly as claimed in claim 1 ;
wherein the shifting tool is biased to the retracted position.

11. The bottomhole assembly as claimed in claim 1 ;
wherein:
the outwardly displacement of the first gripper surface to the first gripper surface gripping position is outwardly relative to the first mandrel; and
the outwardly displacement of the second gripper surface to the second gripper surface gripping position is outwardly relative to the first mandrel.

12. The bottomhole assembly as claimed in claim 11 ;
wherein:
movement of the first gripper surface, during the outwardly displacement of the first gripper surface to the first gripper surface gripping position, includes a rotational component; and
movement of the second gripper surface, during the outwardly displacement of the second gripper surface to the second gripper surface gripping position, includes a rotational component.

13. The bottomhole assembly as claimed in claim 1 ;
wherein:
the displacement of the first gripper surface to the first gripper surface gripping position is such that the first gripper surface becomes disposed for transmitting a force to the flow control member for effecting downhole displacement of the flow control member relative to the port; and
the displacement of the second gripper surface to the second gripper surface gripping position is such that the second gripper surface becomes disposed for transmitting a force to the flow control member for effecting uphole displacement of the flow control member relative to the port.

14. The bottomhole assembly as claimed in claim 1 ;
wherein the shifting tool is supported on the first mandrel.

15. The bottomhole assembly as claimed in claim 1 ;
wherein at least one of the first and the second shifting tool actuators is retained to the first mandrel by at least a shear pin.

16. The bottomhole assembly as claimed in claim 1 ;
wherein;
the second mandrel includes a locator and a collet, wherein the locator is connected to the collet,
the locator is configured for becoming disposed within the locate profile such that the disposition of the second mandrel within the locate profile is effected; and
the collet is configured to exert a biasing force for urging the locator into disposition within the locate profile.

17. The bottomhole assembly as claimed in claim 1 ;
wherein the second mandrel is disposed about the first mandrel.

18. The bottomhole assembly as claimed in claim 17 ;
wherein the first mandrel is displaceable t
