Extreme Dual Magnumdisk™ - Frangible Knockout Isolation Sub
Innovation Revealed:

The EXTREME Dual Magnumdisk™ isolates wellbore reservoir pressure utilizing two dome shaped disks. The Magnumdisks™ are made of a proprietary material which give them incredible strength and durability in a variety of downhole conditions up to 15,000PSI (103.4MPa).

The EXTREME Magnumdisk™ Sub is run on the bottom of the tubing and/or below a production packer BHA. After the production packer is set with EXTREME Dual Magnumdisks™, the wellbore reservoir is isolated. Once the upper production BHA is run in hole, latched in to the packer, and all tests are performed, the Magnumdisks™ can be knocked-out using a Magnum Go-Devil Drop Bar, coil tubing, slickline, or sand line. Once the disks are removed, the wellbore fluids can then be produced up the
