PRH-4 Packer

PRH-4 Hydraulic Set Retrievable Packer

STAR PRH-4 packer is designed to be run with Electric Submersible Pumps. The packer is a hydraulic-set, straight pull shear release, upper single-string, double-bore retrievable packer.

The packer with several additional optional ports allows venting of annular pressure, fluid injection through the packer, and/or instrument wire port bypass. The vent valve is designed to be threaded to the top of the packer.  The valve is hydraulically operated and allows for gas bypass around the packer.  The packer comes with a plug for when the vent valve is not used.
