HYDRAULIC PRODUCTION PACKER

The packer is run as a part of a tubing string and installed hydraulically with conventional techniques while retrieving is achieved by straight pull to release the packer. It provides sealing between the tubing annulus and the casing in the cased hole scenario. Double slips feature enables high pressure applications. The packer release system in the upper slips reduces stress required for slips releasing. The packer is installed by applying pressure directly into the tubing, which can be plugged by dropping the ball into the seat below the packer depth or by setting the slickline plug into the profile nipple below the packer.
