Abstract
A well tool to be oriented and secured in a wellbore without the external application of torque, and a well system incorporating the same. After installation of orientation casing and universal latch coupling casing, the self-orienting selective lockable latch well tool is run downhole to the target depth, picked up to free the internal locking mechanism, and then loaded with downhole stress to engage the locking mechanism.
Claims18
An apparatus comprising:
- a cylindrical housing having a circumferential radially compressible protrusion;
- a mandrel coaxial with the cylindrical housing and forming an annular volume between an inner surface of the cylindrical housing and the mandrel;
- a circumferential support element that is at least partially within the annular volume, wherein the circumferential support element is to reinforce the circumferential radially compressible protrusion against compression;
- a movable circumferential dog attached coaxially to the cylindrical housing and is reversibly compressible into an axis of the cylindrical housing;
- a first releasable connection element attached to the movable circumferential dog;
- and
- a compressed spring positioned to move the movable circumferential dog axially upon shearing of the first releasable connection element.

A system comprising:
- a first tubular housing with a circumferential latch profile and an internal circumferential shoulder disposed on an inner surface of the first tubular housing;
- a second tubular housing coupled with the first tubular housing, wherein an orientation profile is disposed on an inner surface of the second tubular housing;
- and
- a downhole tool comprising:
- an orientation tool positionable within the second tubular housing, wherein an orientation protrusion of the orientation tool is operably engageable with the orientation profile of the second tubular housing;
- a cylindrical housing having a circumferential radially compressible protrusion, wherein the cylindrical housing is coupled with the orientation tool;
- a mandrel coaxial with the cylindrical housing and forming an annular volume between the inner surface of the cylindrical housing and the mandrel;
- a circumferential support element that is at least partially within the annular volume, wherein the circumferential support element reinforces the circumferential radially compressible protrusion against compression;
- and
- a movable circumferential dog attached coaxially to the cylindrical housing and is reversibly compressible into an axis of the cylindrical housing.

A method comprising:
- lowering a well tool having a cylindrical housing into a well until the cylindrical housing is positioned in an interior of a first tubular housing,
- wherein a circumferential support element is secured in an unlocked position in an annular volume within the well tool by a first releasable connection element;
- applying a first axial upward load on the well tool to operably engage a movable circumferential dog attached to the well tool with an internal shoulder on an inner surface of the first tubular housing;
- applying a second axial upward load on the well tool until the first releasable connection element releases;
- and
- applying an axial run-in load on the well tool until a second releasable connection element secures the circumferential support element in a locked position in the annular volume where the circumferential support element supports a circumferential radially compressible protrusion of the cylindrical housing against compression.
