Abstract

There is provided a downhole tool comprising a locator. The locator includes a wellbore coupler for becoming releasably retained relative to a locate profile; and a wellbore coupler release opposer configured for opposing release of the wellbore coupler from the retention relative to the locate profile. While the opposing of the release of the wellbore coupler from the retention relative to the locate profile is being effected by the wellbore coupler release opposer, relative displacement between the wellbore coupler release opposer and the wellbore coupler is effectible, with effect that the opposing is defeated. The locator also includes a displacement impeder for impeding the relative displacement between the wellbore coupler release opposer and the wellbore coupler.

First claim

The invention claimed is:

1. A downhole tool comprising:
a locator including:
a wellbore coupler for becoming releasably retained relative to a locate profile; and
a wellbore coupler release opposer configured for opposing release of the wellbore coupler from the retention relative to the locate profile;

wherein the wellbore coupler and the wellbore coupler release opposer are co-operatively configured such that, while the opposing of the release of the wellbore coupler from the retention relative to the locate profile is being effected by the wellbore coupler release opposer, relative displacement between the wellbore coupler release opposer and the wellbore coupler is effectible, with effect that the opposing is defeated;
and
a displacement impeder for impeding the relative displacement between the wellbore coupler release opposer and the wellbore coupler;
wherein the wellbore coupler release opposer and the displacement impeder are relatively positionable such that:
while:
the wellbore coupler release opposer and the displacement impeder are co-operatively disposed in a first orientation;
the wellbore coupler is releasably retained relative to the locate profile;
release of the wellbore coupler from retention relative to the locate profile is being opposed by the wellbore coupler release opposer;
relative displacement between the wellbore coupler release opposer and the wellbore coupler is being effected while the release is being opposed by the wellbore coupler release opposer;

the relative displacement between the wellbore coupler release opposer and the wellbore coupler, while the release is being opposed by the wellbore coupler release opposer, is impeded by the displacement impeder;
and while:
the wellbore coupler release opposer and the displacement impeder are co-operatively disposed in a second orientation;
the wellbore coupler is releasably retained relative to the locate profile; and
release of the wellbore coupler from retention relative to the locate profile is being opposed by the wellbore coupler release opposer;
relative displacement between the wellbore coupler release opposer and the wellbore coupler, is being effected while the release is being opposed by the wellbore coupler release opposer;

impeding of the relative displacement between the wellbore coupler release opposer and the wellbore coupler, by the displacement impeder, while the release is being opposed by the wellbore coupler release opposer, is prevented or substantially prevented.

2. The downhole tool as claimed in claim 1 ;
wherein the wellbore coupler release opposer is configured for impeding the release of the wellbore coupler from the retention relative to the locate profile.

3. The downhole tool as claimed in claim 1 ;
wherein the wellbore coupler release opposer is configured for preventing the release of the wellbore coupler from the retention relative to the locate profile.

4. The downhole tool as claimed in claim 1 ;
wherein the relative displacement between the wellbore coupler release opposer and the wellbore coupler is a displacement of the wellbore coupler release opposer relative to the wellbore coupler.

5. The downhole tool as claimed in claim 1 , further comprising:
a displacement impeder actuator; and
an actuator receiver;
wherein:
relative rotation between the displacement impeder actuator and the actuator receiver is effectible;
the displacement impeder actuator, the actuator receiver, the wellbore coupler release opposer, and the displacement impeder are co-operatively configured such that a change in the co-operative disposition of the wellbore coupler release opposer and the displacement impeder from the first orientation to the second orientation is effectible in response to the relative rotation between the displacement impeder actuator and the actuator receiver.

6. The downhole tool as claimed in claim 5 , further comprising:
a j-tool for mediating the relative rotation between the displacement impeder actuator and the actuator receiver.

7. The downhole tool as claimed in claim 5 ;
wherein:
the displacement impeder actuator includes a first castellation;
the actuator receiver includes a second castellation; and
the impeding is based on orientation of the first castellation relative to the second castellation.

8. The downhole tool as claimed in claim 1 ;
wherein:
the displacement impeder includes a fluid disposed within a fluid conductor; and
the fluid, the fluid conductor, the wellbore coupler, and the wellbore coupler release opposer are co-operatively configured such that, while relative displacement between the wellbore coupler release opposer and the wellbore coupler is being effected, relative displacement between the fluid and the fluid conductor is effected in response to the relative displacement between the wellbore coupler release opposer and the wellbore coupler, with effect that the impeding of the relative displacement between the wellbore coupler release opposer and the wellbore coupler is effected.

9. The downhole tool as claimed in claim 1
wherein the displacement impeder includes a resilient member for effecting the impeding of relative displacement between the wellbore coupler release opposer and the wellbore coupler.

10. The downhole tool as claimed in claim 1 , further comprising:
a gripper; and
a gripper actuator configured for actuating the gripper;
wherein the gripper, the gripper actuator, the wellbore coupler release opposer and the displacement impeder are co-operatively configured such that:
while the wellbore coupler release opposer and the displacement impeder are co-operatively disposed in the first orientation, actuation of the gripper by the gripper actuator is prevented or substantially prevented; and
while the wellbore coupler release opposer and the displacement impeder are co-operatively disposed in the second orientation, actuation of the gripper by the gripper actuator is effectible.

11. The downhole tool as claimed in claim 1 , further comprising:
a gripper; and
a gripper actuator configured for actuating the gripper;
wherein the gripper, the gripper actuator, the wellbore coupler release opposer and the displacement impeder are co-operatively configured such that:
while the wellbore coupler release opposer and the displacement impeder are co-operatively disposed in the first orientation, displacement of the gripper actuator, relative to the gripper, for effecting actuation of the gripper by the gripper actuator, is prevented or substantially prevented; and
while the wellbore coupler release opposer and the displacement impeder are co-operatively disposed in the second orientation, displacement of the gripper actuator, relative to the gripper, is effectible for effecting actuation of the gripper by the gripper actuator.

12. The downhole tool as claimed in claim 11 ;
wherein the displacement of the gripper actuator, relative to the gripper, is mediated by the j-tool.

13. A system comprising a wellbore and the downhole tool as claimed in claim 1 , wherein the downhole tool is disposed within the wellbore.

14. The system as claimed in claim 13 , wherein the wellbore includes the locate profile.

15. The system as claimed in claim 14 , further comprising a wellbore string lining the wellbore, wherein the locate profile is defined within the wellbore string.

16. A downhole tool comprising:
a locator including:
a wellbore coupler displaceable between an extended position and a retracted position; and
a wellbore coupler displacement-opposing member configured for opposin
