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.

Packer release compaction joint

A weight down collet includes a mandrel that provides an outer diameter feature and a shoulder, and a collet sleeve assembly movably disposed about the mandrel. The collet sleeve assembly includes a body, a primary collet provided on the body and defining an upper detent and a lower detent having a gap defined therebetween, and a secondary collet provided on the body and axially spaced from the primary collet. The upper and lower detents extend radially outward from the body and are engageable with one or more restrictions provided on an inner wall of a completion string, and the secondary collet defines an inner detent that extends radially inward and is engageable with the shoulder. The collet sleeve assembly is movable between an unsupported position, where the primary collet is radially unsupported, and a supported position, where the primary collet is radially supported on the outer diameter feature.

An apparatus for isolating a first zone from a second zone in a subterranean wellbore. The apparatus includes an outer tubular and an inner tubular disposed within the outer tubular forming an annular flow path therebetween that is in fluid communication with the first zone. The inner tubular defines a central flow path that is in fluid communication with the second zone. A sleeve having at least one seal is positioned in the annular flow path and is axially movable relative to the inner and outer tubulars between a closed position wherein the seal engages the inner tubular and an open position wherein the seal engages the outer tubular. A mandrel is slidably disposed within the inner tubular and is coupled to the sleeve. The mandrel is operable to shift the sleeve between the open position and the closed position responsive to changes in pressure within the central flow path.
