Abstract

Certain aspects are directed to a device designed to relieve compression in a length of pipe. The device provides a load ring that can absorb and isolate load until a shear sleeve is shifted and shear pins are sheared. A specific aspect provides a packer release compaction joint that has a shifting sleeve having a first internal shoulder configured to engage a shifting tool; a shear sleeve having a raised abutment; a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned forward of the first side of the raised abutment; a snap ring mounted around the outer diameter of the load ring. Action of a shifting tool against the first internal shoulder of the shifting sleeve causes the snap ring to move away from the load ring and move to the second side of the raised abutment.

First claim

What is claimed is:

1. A release compaction joint tool, comprising:
(a) a shifting sleeve having a first internal shoulder configured for engagement with a shifting tool;
(b) a shear sleeve having a raised abutment;
(c) a load ring mounted on the shear sleeve by a shear element when the release compaction joint is in compression, the load ring having an outer diameter and positioned on a first side of the raised abutment; and
(d) a snap ring mounted around the outer diameter of the load ring when the release compaction joint is in compression, wherein when the release compaction joint tool is shifted, the shear sleeve moves such that the snap ring is located on a second side of the raised abutment.

2. The release compaction joint of claim 1 , further comprising a mandrel and one or more shear elements securing the mandrel to the shear sleeve.

3. The release compaction joint of claim 1 , further comprising an outer tubing with a cavity defined by a ledge against which the snap ring abuts when the release compaction joint is shifted.

4. The release compaction joint tool of claim 1 , wherein action of a shifting tool against the internal shoulder of the shifting sleeve releases compression.

5. The release compaction joint of claim 1 , further comprising
(e) a mandrel in abutment with the snap ring and
(f) an end joint, wherein the mandrel and the end joint are moveable with respect to one another.

6. A packer release compaction joint tool, comprising:
(a) a shifting sleeve having a first internal shoulder configured for engagement with a shifting tool;
(b) a shear sleeve having a raised abutment;
(c) a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned on a first side of the raised abutment; and
(d) a snap ring mounted around the outer diameter of the load ring, wherein the snap ring is C-shaped with a gap in its circumference.

7. A packer release compaction joint tool, comprising:
(a) a shifting sleeve having a first internal shoulder configured for engagement with a shifting tool;
(b) a shear sleeve having a raised abutment;
(c) a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned on a first side of the raised abutment;
(d) a snap ring mounted around the outer diameter of the load ring,
(e) a mandrel in abutment with the snap ring;
(f) an end joint, wherein the mandrel and the end joint are moveable with respect to one another, and
(g) one or more shear elements between the shear sleeve and the mandrel.

8. The packer release compaction joint of claim 7 , wherein the packer release compaction joint is configured to be run into a wellbore with tubing, and wherein the mandrel and end joint extend from an end of the tubing to create a distance between the end joint and the tubing.

9. The packer release compaction joint of claim 8 , wherein action of a shifting tool against the first shoulder of the shifting sleeve causes the end joint to move up to close the distance between the end joint and the tubing.

10. A release compaction joint, comprising:
(a) a shifting sleeve having a first internal shoulder for engagement with a shifting tool;
(b) a shear sleeve having a raised abutment and an end abutting the shifting sleeve;
(c) a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned on a first side of the raised abutment;
(d) a snap ring mounted around the other diameter of the load ring;
(e) a mandrel that applies compressive loads to the snap ring, which are absorbed by the load ring, wherein the mandrel is removable secured to the shear sleeve via one or more shear elements;
(f) an end joint that is moveable with respect to the mandrel;
(g) a space created between the mandrel and the end joint when the packer release joint is in a first compression position, wherein shifting of the shifting sleeve and the shear sleeve to shear the shear elements causes movement of the end joint to close the space.

11. The packer release compaction joint of claim 10 , further comprising an outer tubing with a cavity defined by a ledge against which the snap ring abuts when the packer release compaction joint is shifted.

12. The packer release compaction joint of claim 11 , wherein action of a shifting tool against the first internal shoulder of the shifting sleeve causes the snap ring to slide over the load ring, the shifting sleeve and the shear sleeve to move under the outer tubing, and the snap ring to move into the cavity.

13. The packer release compaction joint of claim 10 , wherein action of a shifting tool against the first internal shoulder of the shifting sleeve releases the first compression position.

14. A method for isolating load on a pipe from shear compression, comprising:
(a) providing a release joint comprising:
(i) a shifting sleeve having a first internal shoulder for engagement with a shifting tool;
(ii) a shear sleeve having a raised abutment and an end abutting the shifting sleeve;
(iii) a load ring mounted on the shear sleeve, the load ring having an outer diameter and positioned on a first side of the raised abutment;
(iv) a snap ring mounted around the other diameter of the load ring;
(v) a mandrel that applies compressive loads to the snap ring, which are absorbed by the load ring, where in the mandrel is removably secured to the shear sleeve via one or more shear elements;
(vi) an end joint is moveable with respect to the mandrel;

(b) providing a shifting tool;
(c) engaging the shifting tool with the first internal shoulder of the shifting sleeve;
(d) applying force to the shifting tool.

15. The method of claim 14 , wherein applying force to the shifting tool causes movement of the shifting sleeve and the shear sleeve, causes a shear of the one or more shear elements, and causes movement of the snap ring away from the load ring.

16. The method of claim 14 , wherein action of a shifting tool against the first internal shoulder of the shifting sleeve causes the snap ring to slide over the load ring.

17. The release compaction joint tool of claim 16 , wherein the shifting sleeve comprises a second shoulder to abut a shear sleeve.
