Abstract: A housing, mandrel and bearing assembly positionable in a wellbore includes a torque transmission member adapted to connect to a source of rotational torque (e.g. a downhole motor power output) and a tubular mandrel adapted to connect to a drill bit. A lower tubular housing is adapted to contain a lower bearing and catch sleeve assembly. The catch assembly is adapted to retain the mandrel in the lower housing if the mandrel breaks. An upper tubular housing contains an upper bearing and is adapted to connect to a housing of the downhole motor. A method of assembling the downhole housing, mandrel and bearing assembly is disclosed.

Abstract: A disconnect tool includes a bottom housing having a central longitudinal axis, a top housing, a release piston, and a shear sleeve. The bottom housing includes an internal torque transmission portion and an internal locking portion. The top housing includes a lower portion positioned within the bottom housing, where the outer surface includes an external locking portion to engage the internal locking portion of the bottom housing and an external torque transmission portion to engage the internal torque transmission portion of the bottom housing. The release piston translates longitudinally within the top housing along the central longitudinal axis from a locked position to an unlocked position. The shear sleeve secures the release piston in the locked position and disconnects from the release piston at a threshold force on the release piston to allow the release piston to translate along the central longitudinal axis to the unlocked position.
