Abstract

A system includes a downhole tool assembly extendable within a wellbore. A running tool axially interposes the downhole tool assembly and the conveyance and includes an elongate body providing an interior and one or more radial protrusions. A connection sub is disposed about the body and provides a releasable connection engageable with the downhole tool assembly. A torque sleeve is disposed about the body and at least a portion of the connection sub. A connection sub piston interposes the body and the connection sub and is axially movable between a supported position, where the connection sub piston radially supports the connection sub, and an unsupported position, where at least a portion of the connection sub is radially unsupported by the connection sub piston. Increasing pressure within an annulus between the running tool and the wellbore moves the connection sub piston from the supported position to the unsupported position.
