... valves consist of Surface controlled Subsurface Safety Valve (SCSSV), Surface Safety Valve (SSV) and Flowing Wing Valve (FWV) which may centrally control by Wellhead Control Hydraulic Panel (WHCP) via hydraulic systems. Routine test is conducted to ensure valves able to isolate hydrocarbon source during...

... This paper discusses validation and verification considerations for large-bore sub-surface safety valves, particularly with respect to use in natural gas completions producing high flow rates to 450 MMSCFD and beyond. With natural gas wells, it is generally desirable from an economic standpoint...
