Isolation assurance against fluid migration plus multiple-stage cementing support
Reliable and effective annular barriers are critical to well management for safety and performance. When sustained casing pressure (SCP) occurs, it is an indication that well integrity has been compromised, often resulting from a failed barrier. SCP can lead to a loss of production and costly remediation.
The Obex IsoLock casing packer collar, which is part of the Halliburton Obex™ family of compression-set packers, provides a mechanical barrier that bridges the cost and capability gap between an inflatable casing packer/cementer and a premium gas-tight casing packer and cementer run in tandem. By integrating a casing packer and cementer into a single assembly, the Obex IsoLock casing packer collar can prevent well integrity issues, even after the second cement stage is complete. Built upon our gas-tight Obex™ GasLock™ V0-rated design, the Obex IsoLock casing packer collar provides increased reliability and ISO 14310 V3-rated pressure holding capacity over inflatable casing packer options.
