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; and
a locator release impeder;
wherein:
the downhole tool is configurable in a locator release-resisting configuration and a locator release-compliant configuration;
in the locator release-resisting configuration, the locator and the locator release impeder are co-operatively oriented such that, while the locator is being retained within a locate profile within a wellbore, and a sufficient force is being applied for releasing the locator from the retention, the locator becomes released from the retention and the releasing is impeded by the locator release impeder for impeding the release;
in the locator release-compliant configuration, the locator and the locator release impeder are co-operatively oriented such that, while the locator is being retained within a locate profile within a wellbore, and a sufficient force is being applied for releasing the locator from the retention, the locator is released from the retention and there is an absence of impeding of the releasing by the locator release impeder; and
transition from the locator release-resisting configuration to the locator release-compliant configuration is effectible in response to relative rotation between the locator release impeder and the locator.

2. The downhole tool as claimed in claim 1 , further comprising:
a j-tool for mediating the relative rotation between the locator release impeder and the locator.

3. The downhole tool as claimed in claim 1 ;
wherein:
the locator release impeder includes a first castellation;
the locator includes a second castellation; and
the impeding is dependent on orientation of the first castellation relative to the second castellation.

4. The downhole tool as claimed in claim 1 , further comprising:
a shifting tool; and
a shifting tool actuator configured for actuating the shifting tool;
wherein the shifting tool, the shifting tool actuator, the locator and the locator release impeder are co-operatively configured such that:
while the locator and the locator release impeder are co-operatively disposed in the locator release-resisting configuration, actuation of the shifting tool by the shifting tool actuator is prevented; and
while the wellbore coupler release opposer and the locator release impeder are co-operatively disposed in the locator release-compliant configuration, actuation of the shifting tool by the shifting tool actuator is effectible.

5. The downhole tool as claimed in claim 1 ;
wherein:
the relative rotation between the locator release impeder actuator and the locator is effectible about an axis and in response to a force applied along the axis.

6. A system comprising a wellbore and the downhole tool as claimed in claim 1 ;
wherein:
the downhole tool is disposed within the wellbore.

7. The system as claimed in claim 6 ;
wherein:
the wellbore includes the locate profile.

8. The system as claimed in claim 7 :
further comprising:
a wellbore string lining the wellbore, wherein the locate profile is defined within the wellbore string.

9. A downhole tool comprising:
a locator including a wellbore coupler displaceable between an extended position and a retracted position;
a wellbore coupler retraction impeder;
wherein:
the downhole tool is configurable in a wellbore coupler retraction-resisting configuration and a wellbore coupler retraction-compliant configuration;
in the wellbore coupler retraction-resisting configuration, the wellbore coupler and the wellbore coupler retraction impeder are co-operatively oriented such that, while the wellbore coupler is disposed in the extended position, and a sufficient force is being applied for retracting the wellbore coupler from the extended position, the wellbore coupler becomes retracted from the extended position and the retraction is impeded by the wellbore coupler retraction impeder;
in the wellbore coupler retraction-compliant configuration, the wellbore coupler and the wellbore coupler retraction impeder are co-operatively oriented such that, while the wellbore coupler is disposed in the extended position, and a sufficient force is being applied for retracting the wellbore coupler from the extended position, the wellbore coupler is retracted from the extended position and there is an absence of impeding of the retraction by the wellbore coupler retraction impeder; and
transition from the wellbore coupler retraction-resisting configuration to the wellbore coupler retraction-compliant configuration is effectible in response to relative rotation between the wellbore coupler retraction impeder and the wellbore coupler.

10. The downhole tool as claimed in claim 9 , further comprising:
a j-tool for mediating the relative rotation between the wellbore coupler retraction impeder and the wellbore coupler.

11. The downhole tool as claimed in claim 9 ;
wherein:
the wellbore coupler retraction impeder includes a first castellation;
the wellbore coupler includes a second castellation; and
the impeding is dependent on orientation of the first castellation relative to the second castellation.

12. The downhole tool as claimed in claim 9 , further comprising:
a shifting tool; and
a shifting tool actuator configured for actuating the shifting tool;
wherein the shifting tool, the shifting tool actuator, the wellbore coupler and the wellbore coupler retraction impeder are co-operatively configured such that:
while the wellbore coupler and the wellbore coupler retraction impeder are co-operatively disposed in the wellbore coupler retraction-resisting configuration, actuation of the shifting tool by the shifting tool actuator is prevented; and
while the wellbore coupler retraction opposer and the wellbore coupler retraction impeder are co-operatively disposed in the wellbore coupler retraction-compliant configuration orientation, actuation of the shifting tool by the shifting tool actuator is effectible.

13. The downhole tool as claimed in claim 9 ;
wherein:
the relative rotation between the wellbore coupler retraction impeder actuator and the wellbore coupler is effectible about an axis and in response to a force applied along the axis.

14. A system comprising a wellbore and the downhole tool as claimed in claim 9 :
wherein:
the downhole tool is disposed within the wellbore.

15. A downhole tool coupled to a conveying member comprising:
a wellbore coupler displaceable between an extended position and a retracted position; and
a wellbore coupler displacement-opposing member configured for opposing displacement of the wellbore coupler from the extended position to the retracted position;
and
a frangible member effecting the coupling of the displacement opposing member to the conveying member;
wherein:
the wellbore coupler displacement-opposing member, the conveyance member, the frangible member, and the wellbore coupler are co-operatively configured such that, while seated on the wellbore coupler displacement-opposing member, the wellbore coupler becomes friction locked within the wellbore, coupling of the wellbore coupling displacement-opposing member to the conveyance member is defeatable in response to shearing of the frangible member such that the wellbore coupler becomes movable within the wellbore.

16. A system comprising a wellbore and the downhole tool as claimed in claim 15 ;
wherein:
the downhole tool is disposed within the wellbore.
