8″ x 15000psi Drill stem testing super safety valve

Well testing DST Halliburton super safety valve / SSV with control pannel


Introduction of Well testing super safety valve

The Super Safety Valve is a Fail Safe Safety Valve for testing from a land or jack-up rig.  It is normally run inside or

below the Blow Out Preventer (BOP) and is used to control well flow. Its ID is 3.0 in., OD is 8.0 in., and its working

pressure is 15,000 psi.  This valve has a port for chemical injection downhole or to control a subsurface safety valve.

It is capable of cutting wireline and coiled tubing using the nitrogen charge or by application of balance line pressure.

The main function of remote control  system is to control the downhole safety valve in case of emergency situation

to shut off the safety valve. The system contains Three loop, one loop(1) connects with control  line in safety valve,

one loop(2) connects with  balance line, and rest loop(3) connect with a fusible plug.
