- Houston TX, US
Cynthia Strickland Tuckness - Coppell TX, US
Jeremy Lynn Stanley - McKinney TX, US
Bruce Alan Moore - Highland Village TX, US

International Classification:

E21B 33/128
E21B 23/06

Abstract:

Disclosed herein are embodiments of a packer assembly and a well system. In one embodiment, a packer assembly includes an inner mandrel; a packing element at least partially surrounding the inner mandrel; a packing element activation sleeve coupled to the packing element; a hydrostatic setting assembly engageable with the packing element activation sleeve; and a hydraulic setting assembly positioned between the packing element and the hydrostatic setting assembly. The hydrostatic setting assembly includes a hydrostatic piston; a hydrostatic prop piston engageable to push the hydrostatic piston to engage the packing element activation sleeve; and a hydrostatic locking mechanism to maintain the hydrostatic piston in a locked position. The hydraulic setting assembly includes a hydraulic piston; a hydraulic locking mechanism coupled to the hydraulic piston; and a hydraulic prop piston engageable with the hydraulic locking mechanism and operable to move the hydraulic locking mechanism between locked and unlocked position.

Abstract:

A collet lock assembly for use on a downhole tool allows repeat cycling of a “RELEASE” and “SET” position. In the “RELEASE” position, the collet lock assembly allows bi-directional relative movement of the mandrel in relation to the collet lock assembly, while in the “SET” position, the assembly allows bi-directional load transfer along the mandrel directly into the slip assembly while diverting axial loads away from components positioned along the downhole tool.
