The Free Gas Vent Mandrel (FGV) is made up in the tubing string at a depth above the packer. The system is designed for lower risk environments such as shallow set, non-deviated wells or land applications and allows gas, under pressure to move, uncontrolled from below the packer into the tubing above the packer.
There is no communication via control line to the surface and therefore the system operates based on pressure build up in the control line exceeding the tubing pressure and bleeding into the tubing through the integral checks and hence providing protection to the pump.
Electrical Submersible Pump (ESP) Installations
Tubing deployed as part of production string
Allows the venting of any gas build up from below the packer to the upper annulus
Materials to suit all well environments
Available in multiple configurations
Allows adequate gas removal and prevent pump failure due to gas locking
Adapts to multi-port packers
In tight applications it improves the geometry at the packer.
Allows fluid level below packer to be maintained at optimal levels for ESP operation
Optional thread makeup connections
