Compression-set mechanical barrier support

Superior sealing performance

Each wellbore presents a unique set of challenges for achieving effective zonal isolation. The Obex® family of compression-set casing annulus packers can address a range of complex wellbore conditions, providing effective mechanical barriers to prevent sustained casing pressure, reach top of cement (TOC), and maximize production. 

Reliability by design

The Obex Packer Family - Obex GasLock®, Obex IsoLock®,  Obex EcoLock® 

• 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 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 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 packer from fully setting.
• Element seal engineered for performance
  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 fail to maintain a seal over time.
