The CHSJ is a high-performance hydraulic set packer designed as a cased-hole anchor for multi-stage stimulation applications.
As a critical part of the Zone Seeker system, this packer provides secure, reliable annular pressure isolation, and liner anchoring during formation treatments. A simple and compact design lets operators deploy and handle it with ease, even in the most troublesome wells. An integral polished bore receptacle and on/off overshot profile provide a solid and reliable interface with the systems deployment tool. The CHSJ is set by applying pressure to the tubing string, and a high-performance fully retained packing element reliably holds extreme differential pressures from above and below through multiple pressure and direction cycles.
Compact design provides ease of handling, eliminates the need for handling joints, reduces leak paths, and significantly increases rig floor safety
