Abstract

An indicating tool includes a mandrel including a support, an indicator housing surrounding the mandrel, and a member movable radially with respect to the housing. The mandrel is movable longitudinally with respect to the indicator housing, and the indicator housing is at least substantially rotationally locked with respect to the mandrel. The member is engageable with an inner profile of an outer tubular in which the indicating tool is employed, and the member has a substantially helical side. The member is movable radially inward towards the mandrel when the support is longitudinally displaced from the member, and the member is blocked from movement radially inwards when the support is longitudinally aligned with the member.

First claim

What is claimed is:

1. An indicating tool having a longitudinal axis and comprising:
a mandrel including a support, the support including a helical shape disposed helically around the longitudinal axis;
an indicator housing surrounding the mandrel, the mandrel movable longitudinally with respect to the indicator housing, and the indicator housing at least substantially rotationally locked with respect to the mandrel; and,
a member movable radially with respect to the housing, the member engageable with an inner profile of an outer tubular in which the indicating tool is employed, the member having a substantially helical side disposed helically around the longitudinal axis;
wherein the member is movable radially inward towards the mandrel when the support is longitudinally displaced from the member, and the member is blocked from movement radially inwards when the support is longitudinally aligned with the member.

2. The indicating tool of claim 1 , wherein the member protrudes outwardly from the indicator housing.

3. The indicating tool of claim 1 , wherein the substantially helical side includes a plurality of spaced helical side portions disposed helically around the longitudinal axis.

4. The indicating tool of claim 1 , wherein the indicator housing includes a collet, and the member includes a plurality of nubs of the collet, each nub including a portion of the substantially helical side, the nubs disposed helically around the longitudinal axis.

5. The indicating tool of claim 4 , wherein the collet includes a plurality of radially deflectable segments, each segment including a first end and a second end, the first and second ends attached to the housing, and each segment carrying one of the plurality of nubs between the first and second ends.

6. The indicating tool of claim 1 , wherein the member includes at least one dog, the at least one dog including at least a portion of the substantially helical side.

7. The indicating tool of claim 6 , wherein the indicator housing includes a plurality of openings arranged in a helical pattern, the at least one dog includes a plurality of dogs, and each opening in the plurality of openings is arranged to receive a respective one of the plurality of dogs there through.

8. The indicating tool of claim 1 , wherein the mandrel includes a longitudinal keyway, and further comprising a key movable with the housing and within the keyway, wherein the key rotationally locks the housing with respect to the mandrel.

9. The indicating tool of claim 1 , wherein the member has a first end and a second end, and the member includes a first helical member portion and a second helical member portion, the first helical member portion extending a half turn of a helix from the first end to the second end of the member in a clockwise direction with respect to the longitudinal axis of the indicating tool, and the second helical member portion extending a half turn of a helix from the first end to the second end of the member in a counterclockwise direction with respect to the longitudinal axis.

10. The indicating tool of claim 1 , wherein an outer diameter of the tool at a radially outwardly facing surface of the member is greater than an outer diameter of the tool at an outer surface of the housing.

11. The indicating tool of claim 1 , further comprising an indexing arrangement.

12. An indicating tool having a longitudinal axis and comprising:
a mandrel including a support;
an indicator housing surrounding the mandrel, the mandrel movable longitudinally with respect to the indicator housing, and the indicator housing at least substantially rotationally locked with respect to the mandrel;
a member movable radially with respect to the housing, the member engageable with an inner profile of an outer tubular in which the indicating tool is employed, the member having a substantially helical side disposed helically around the longitudinal axis; and
an indexing arrangement including an orientation sleeve surrounding the mandrel and having an indexing slot, an indexing housing surrounding the orientation sleeve, and a lug movable with the indexing housing and within the indexing slot, the mandrel movable longitudinally with respect to the indexing housing;
wherein the member is movable radially inward towards the mandrel when the support is longitudinally displaced from the member, and the member is blocked from movement radially inwards when the support is longitudinally aligned with the member.

13. The indicating tool of claim 12 , wherein the orientation sleeve is fixed with respect to the mandrel.

14. An indicating tool having a longitudinal axis and comprising:
a mandrel including a support;
an indicator housing surrounding the mandrel, the mandrel movable longitudinally with respect to the indicator housing, and the indicator housing at least substantially rotationally locked with respect to the mandrel;
a member movable radially with respect to the housing, the member engageable with an inner profile of an outer tubular in which the indicating tool is employed, the member having a substantially helical side disposed helically around the longitudinal axis; and
a spring surrounding the mandrel and biasing the support longitudinally away from the member;
wherein the member is movable radially inward towards the mandrel when the support is longitudinally displaced from the member, and the member is blocked from movement radially inwards when the support is longitudinally aligned with the member.

15. A completion system comprising:
the indicating tool of claim 1 ; and,
the outer tubular, the inner profile of the outer tubular having a helical profile face.

16. The completion system of claim 15 , wherein, when the indicating tool is moved longitudinally with respect to the outer tubular, the side of the member engages with the helical profile face of the inner profile and the indicating tool moves rotationally with respect to the outer tubular.

17. The completion system of claim 15 ,
wherein engagement of the side of the member with the helical profile face of the inner profile of the outer tubular imparts rotation to the indicating tool during longitudinal movement of the tool within the outer tubular.

18. The completion system of claim 17 , wherein the member is movable radially inward towards the mandrel and the indicating tool is movable past the inner profile when the member is unsupported by the support, and the member is blocked from movement radially inwards and the indicating tool is set within the inner profile when the member is supported by the support.

19. The completion system of claim 17 , further comprising a first unit connected to a first end of the mandrel, wherein movement of the helical side of the member along the helical profile face of the inner profile rotates the first unit with respect to the outer tubular.

20. A method of rotationally locating an inner string within an outer tubular, the method comprising:
running the inner string through the outer tubular towards an inner profile of the outer tubular, the inner string including the indicating tool of claim 1 ;
engaging the helical side of the member with the inner profile of the outer tubular; and,
rotating the inner string with respect to the outer tubular by camming the helical side of the member along a helical profile face of the inner profile.

21. The method of claim 20 , further comprising shifting the mandrel with respect to the indicator housing to at least substantially longit
