PBS AGB

PBS AGB is an axial retrievable mechanical packer with bilateral pressure perception, which is set by unloading the tubing.
The packer is equipped with two anchors - lower mechanical and upper hydraulic. The packer is transferred from the tripping state to the setting state by means of axial manipulations of the tubing. For setting, it is necessary to raise the tubing to a height of at least 2 ft and then unload it with a weight of at least 17,700 lbs. The release of the packer is carried out by direct lifting of the tubing.
The PBS AGB packer is equipped with an end-type bypass valve that controls the flow between the under and above the packer zones and allows equalizing the pressure before stripping. An integrated hydraulic mechanism helps keep the valve closed at high pressures.

• Well Operation
• Well Test, equipment and search for leaks
• Maintenance and workover of wells, in particular cementing of wells, acid treatment of the bottomhole zone and others
• Hydraulic fracturing

• Simplicity and reliability of design
• Setting by axial manipulation of the tubing
• Diverter valve, end type
• The hydraulic anchor is isolated from the flow and triggered by pressure from below
• Unlimited number of landings per Tripping
• Full bore
• Serviceability
