FlowCAT™ Wireless Safety Valve System
Surface Controlled Sub-surface Safety Valves (SCSSVs) are prone to failuredue to plugging or leaks in the hydraulic control line. The common remedial solution involves installing a Sub-surface Controlled Safety Valve (SSCSV), such as a storm choke. These SSCSVs are directly influenced by changing well conditions, such as high flow rates, low pressures, or by water slugs, and thus are notoriously unpredictable in operation. Additionally, 
they are not controllable from surface and not fail-safe, which is undesirable from a well control and safetystandpoint.
Developed with the support of Petrowell Ltd, FlowCAT is a new wireless controlled safety valve system that can be retro-fitted into a well using conventional slickline intervention equipment and procedures. Being controllable from surface and of a fail-safe closed design, this offers both functional and safety advantages over existing SSCSV solutions. The valve system also offers a retro-fittable solution where no hydraulic control line is installed, and where a capillary string may need to be installed for foam injection purposes, it provides an opportunity to free up the hydraulic control line. FlowCAT marks the introduction of a more controllable and predictable alternative to an ambient valve or storm choke, minimises deferred production and increases well safety.
