Electronic Activated Wellbore Integrity g y • Solid-body packer mandrel with tubular
connections – No holes in the pipe
• Electronically activated setting module – Eliminates Eli i t need d ffor pressure or pipe i manipulation to set the packer – Self-contained pressurized gas and/or hydrostatic chambers maintain continuous setting force to enhance seal integrity • Proven (ISO 14310 V0) seal technology
