Legendary reliability for horizontal applications

Using two dome-shaped disks, the Interventionless MagnumDisk reliably isolates wellbore reservoir pressure, eliminating the need for intervention with slickline or coiled tubing. Its proprietary construction provides considerable strength and durability in a variety of downhole conditions. To isolate the tubing and place the hydraulic set packers, the tool is run as an isolation barrier on the bottom of the tubing and/or below the packer BHA. Once tests are performed, a predetermined activation pressure is applied at the surface to remove the MagnumDisks. After removal, wellbore fluids can be produced up the production tubing.

  • Accurate to plus or minus 2% absolute pressure value
  • Field-adjustable activation values
  • Used as a barrier to set hydraulic packers
  • Used to float casing or liners into horizontal wellbores
  • Full-bore opening to tubing/casing ID after the Interventionless MagnumDisk has been activated and disks removed
  • Economical alternative to profile nipple with a plug; eliminates plug and prong removal runs
  • Used to negative test liner top
  • Premium threads available
  • Available with seals and CRA materials for use in hostile environments (H2S and CO2)
  • Can be run in heavy mud environments
  • Rating: 400°F (204°C)
  • Little to no interfering debris left in the wellbore
  • Can be pressure tested prior to installation
  • Used for snubbing applications in live wells*
  • Patent-pending technology

*Nine Energy Service recommends the use of the Interventionless 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.
