Abstract
A hydraulic packer with seals and slips is actuated by first and second cylinders which move in a first direction to actuate the seals or the slips into setting position with primary and secondary pistons carried within the cylindrical members and tandemly arranged for movement in a second direction to activate the other of the seals and slips. The pistons are selectively secured against longitudinal movement relative to the housing and to each other and the primary piston is released from the housing before release of the secondary piston.
