Cost-effective performance under higher pressures

The Extreme Dual MagnumDisk™ barrier valves offer incredible strength and durability for a variety of downhole conditions. Constructed of proprietary materials, it isolates wellbore reservoir pressure via two internal barrier devices. It can be effectively deployed for snubbing, tubing-isolation, and deepwater applications. The sub is run on the bottom of the tubing and/or below a packer BHA to isolate the tubing and act as a barrier to place hydraulic set packers. After all of the tests are performed, the disks are knocked out using a MagnumDisk Drop Bar™, coiled tubing, slickline or sand line. Once disks are removed, wellbore fluids can be produced up the production tubing.

• Used as a barrier to set hydraulic packers
• Allows for tubing tests up to 15,000 psi (103.4 MPa)
• Economical alternative to profile nipple with a plug
• Eliminates plug and prong removal runs
• Full bore opening to tubing ID after MagnumDisks are removed
• Gas-bubble tight rated available
• Used to negative test liner top
• Available with premium threads and materials
• Maximum surge potential of formation after perforating
• Can be run in hostile environments (H₂S and CO₂)
• Rating: 400°F (204°C)
• Can be run in heavy mud environments
• Little to no interfering debris left in the wellbore
• Can be pressure tested prior to installation
• Patented technology
• Used for snubbing applications in live wells*

*Nine Energy Service recommends the use of the Extreme Dual MagnumDisk for snubbing operations, as long as the pressure control company and/or operator have procedures in place to secure/control the well in the unlikely event of tool failure.
