The SUREstack™ RC Millable Valve is a ball activated fracturing sleeve designed for multiple frac stages in a well bore.
High flow circumferential ports located on the housing of the sleeve permits continuous communication to the reservoir for high pressure fracturing operations and production.
This system uses low specific gravity balls, which encourages flow back when the well is put on production.
Specially designed anti-rotational features are incorporated into the sleeve to ensure reliable seat mill-out performance.
Utilizing a designated shifting tool, the valve sleeve can be closed to shut-off water producing intervals or for interval production evaluation.
Features and Benefits
Compact design for ease of handling (no pup joints required)
Improved ball seat geometric features to enhance production capability, ball on seat pressure rating, and ball off seat performance
Simple valve, with only 4 main components
Extremely short valve, allowing for tighter stages
Up to 42 stages when run with a SUREstart™ Valve
Re-closable, designed for open-hole applications
Rated to 400° F (204° C) with standard trim, elastomer upgrades available
The SureStack system with ball-activated frac sleeves and retrievable seats for one run-up operation
The Retrievable Ball Valve is a ball-activated fracturing sleeve, designed to allow for multiple frac stages in a horizontal well bore. Once the well has been fractured, it can either be shut in or flowed back depending on customer preference.
Using a service rig or coiled tubing unit and a special retrieving tool, the seats are retrieved with a simple tag and release method. With its patented design, up to 36 seats can be retrieved in a single trip.
Utilizing a designated shifting tool, the sleeve(s) can then be closed to shut-off water producing intervals or for interval production evaluation. This system utilizes low specific gravity balls which encourage flow back when the well is put on production
Features and Benefits
Reduction of the cost of work – a reduction in the cycle of work after fracturing up to 30%
The ability to start production of the well immediately after the work on the fracturing
Reduction of fluid loss in the reservoir duringcompletion
Ensuring the operation of all open intervals of the horizontal section of the wellbore
Developed equipment for regions with high H2S content
