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.
