PRH-2 Hydraulic Set Retrievable Packer

The Star PRH-2 Packer is a retrievable single-string packer which is designed to be set by plugging the tubing below the packer and applying internal pressure. The packer is retrieved by simply raising the tubing string to shear the release shear pins.
The packer does not require mandrel movement to establish a full set which makes it suitable for multi-packer installations. The packer is capable of hanging heavy tailpipe loads in the casing and is available with selective-set mechanisms.
The packer is suitable for production and injection installations. In addition, service applications such as stimulation and tubing-conveyed perforating operations may also be carried out using this packer taking special precautions to prevent premature shear of the release pins.
