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.
