ABSTRACT:
A packer is disclosed having a setting piston mounted on the body thereof. The packer is hydraulically set prior to treating or cementing. The packer has a sliding sleeve valve which is open during run-in. After the packer has set, the setting tool is released from the valve. The valve may then be operated through manipulation of the tubing string. The tubing string can be disengaged and reengaged into the packer body to determine if the valve has closed by measuring the pressure conditions at the surface.
