Abstract
A retrievable hydraulically operated running tool is run in a wellbore to preform a desired downhole tool activation. The port closure member is movable with a tubular body from a port isolation position to an open port position. A seat supported on the port closure member receives a plug to shift the port closure member to the open port position, wherein the port exposes increased fluid pressure to the piston to move to an activated position. The seat may be deformable for release in the plug from the seat after the port closure member has moved the open port position.
