The Single Magnumdisk™ frangible knockout sub is used to create an underbalance and for workstring isolation. The Magnumdisk™ Sub is run on the bottom of the tubing and/or below a production packer BHA. After the production packer is set with a Single Magnumdisk™, 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 disk can be removed. Although the most common removal method is applying 1,000PSI (6.9MPa) overbalance pressure from surface, a Magnum Go-Devil Drop Bar, coil tubing, slickline, or sand line can also be used. Once the disk is removed, the wellbore fluids can then be produced up the production tubing.
