Performance on both sides

Constructed of proprietary material, the Dual MagnumDisk™ barrier valve offers incredible strength and durability in a variety of downhole conditions, isolating wellbore reservoir pressure via two internal barrier devices. Perfect for snubbing applications, it handles pressure equally from either side, translating to twice the performance. 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 10,000 psi (68.9 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
  • Reusable, with redressing kit
  • Patented technology
  • Used for snubbing applications in live wells*

*Nine Energy Service recommends the use of the 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.
