Obex IsoLock® casing packer collar

Engineered for performance

• Hydromechanical setting method
  An internal ratchet mechanism locks the compression element every 0.060” of set, resulting in zero weak points in the packoff, which can thereby mitigate sustained casing pressure. Because the casing packer is mechanically set and not inflated, it can exceed casing burst and collapse ratings, offering increased dependability.
• Drive-pin setting system 
  Internal casing pressure acting on a plug seat transfers the setting load to the casing packer elements rather than relying on narrow hydraulic channels that can pack off in high density fluids. The drive-pin setting system eliminates potential leak paths from the setting operation. This feature removes the risk of premature rupture disc failure, often affected by losses in the well, which would traditionally prevent the casing packer from fully setting.
• Superior sealing
  Propped packer elements are compressed between backup shoes and a unique spacer. These elements remain energized by the internal ratchet mechanism to deliver an effective seal for the life of the well, offering improved reliability over inflatable and expandable alternatives that can deflate over time.
• Improved drillability
  The compact design of the integrated stage cementer and casing annulus packer allows for two lower-profile seats and 70% fewer internal components compared to traditional stage tool design, which results in simplified drillouts and reduced debris volume.
