ZONE StimStac™ system is a field proven Formation Seal V single-set rotational-release Dual injection packer system. Located between the Formation Seal V packers is a mechanically activated STIMPort™ Treatment Valve which provides for a uniform treatment across the specific zone of the wellbore to be isolated and selectively acid fracture stimulated.
ZONE StimStac™ system is designed to be inflated, deflated and retrieved one time per run. However, the system is capable of being redressed On-Site for additional runs should the job need arise.
The ZONE StimStac™ system is run in the well on threaded pipe (work string) and is inflated with the application of work-string hydraulic pressure. To deflate and retrieve the system, the work-string is pulled upward and then rotated 6 revolutions to the right, allowing pressure between the elements and the annulus above to equalize. An additional pull causes the elements to deflate into the tubing and the annulus below the packers. Once the elements have completely deflated, the system is ready to be retrieved.
