The Magnumdisk™ Isolation Sub is designed to keep the static area below the communication ports completely isolated for TCP operations. To achieve the isolation condition, this tool uses a high strength dome disk that is placed below the flow ports on the sub housing. The ports are used for production, pump volumes, or to simply act as a tubing drain while pulling out of the hole.

• Full opening ID once the disk is shattered
• Maximum Surge Protection

The Magnum Isolation Sub is placed below the packer and should be placed a minimum of 30’ (9.1M) above the mechanical firing head device. Run the TCP guns into the well and one joint of tubing. Fill the tubing with clean fluid and install Isolation Sub. Continue to run TCP assembly to perforation depth. Correlate into position, set and pressure test packer. Release drop bar at surface. The drop bar will shatter the ceramic disk then hammer the firing pin to activate the firing head.
