PHSB Hydraulic Permanent Packer



The model PHSB Hydraulic Permanent Seal Bore Packer is a one trip hydraulic-set packer that combines all the proven features of the high performance model ‘PS’ Permanent Production packer. The model PHSB hydraulic permanent packer uses most of the same accessories as the model ‘PS’ permanent production packer.

The model PHSB is designed for safe, fast running and superior reliability. Metal anti-extrusion rings provide full 360 degree contact with the casing to prevent element extrusion due to high temperature and pressure. All PHSB Hydraulic-Set Permanent Seal Bore Packers come standard with body parts secured in place with anti pre-set shear pins, full circle, one piece opposing case hardened slips, micro honed seal bore and a unique anti swab element design.

The PHSB Packer is run in on the tubing string using a latch seal assembly or PHSB hydraulic setting tool and set using tubing pressure, therefore a blanking device must be installed below the setting ports of the packer before setting. This makes the PHSB an ideal packer for use in high angle deviated wells, or any application in which it is desirable to install the wellhead before setting the packer. A locator seal assembly may be substituted once the packer has been set if required.

As standard, the model PHSB packer is made of materials in accordance with NACE MR-0175 specification for H2S service. The model PHSB is also available in a variety of material and elastomer configurations to suit virtually any hostile environment.
