Abstract

An improved downhole locking mechanism which may include a housing releasably connected to a downhole tool. The housing includes a first housing connected to a second housing. A sleeve disposed within the second housing. A coupling connecting the sleeve and a completion or another assembly. A piston disposed within the sleeve and retained in a locked position via a shear assembly. The piston maintains a retainer in the locked position, where the retainer engages both the sleeve and the lower housing. Hydraulic pressure within the bore of the locking mechanism causes the piston to shear the shear assembly and axially shift the piston towards the upper housing. Shifting the piston causes the retainer to move radially inward to an unlocked position and disengaging the sleeve from the lower housing and unlocking the locking mechanism.
