Single MagnumDisk™

Composed of a proprietary material which offers incredible strength and durability, the Single MagnumDisk™ frangible knockout sub is employed to create an underbalance for work string isolation.

For both snubbing and pump-out applications, Magnum’s Single MagnumDisk™ offers unparalleled efficiency and reliability—and a more economical alternative to traditional methods. Designed to work in a variety of conditions, Single MagnumDisk™ provides a dependable solution for a range of isolation needs.

• Economical alternative to profile nipple with a plug
• Eliminates the use of retrievable plugs
• Can be run in hostile environments (H2S and CO2)
• Can be run in heavy mud environment
• Little to no interfering debris left in the wellbore

The MagnumDisk™ Sub is run on the bottom of the tubing or below a production packer BHA. Once the production packer is set with a Single MagnumDisk™ or ran on the bottom of the tubing string, the wellbore reservoir is isolated. After the upper production BHA is run in hole, latched in to the packer, and all tests are performed, the disk can be pumped out.

Although the most common removal method is applying 1,000PSI (6.9MPa) overbalance pressure from surface to pump out the Single MagnumDisk™, 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.

• Used for snubbing applications in live wells
• 400°F (204ºC) rated
• Fully open after disk is removed
• Reusable, with redressing kit and simple assembly procedure
• Available with premium threads and materials
• Can be pressure tested previous to installation
• Patent #5924696
