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.
