Maximum Differential Bar Vent
The Maximum Differential Bar Vent Assembly is a vent run between the perforating guns and the packer. After the packer is set, the opening of the vent creates communication between the tubing and the rathole. The vent is opened by breaking the plug inside the tool and allowing the sleeve to uncover the ports. Running the Maximum Differential Bar Vent allows the operator to run the tubing in the well with no hydrostatic pressure in the tubing.
