Oil Well Testing Super Safety Valve High Pressure DST Working String


The Super Safety Valve is the BOP safety valve applied for testing operations from jack-up or land rigs. It can rapidly closes the test string in an emergency, serves as a fail safe safety Valve for well testing. And during the well testing, the Super Safety valve is featured with capablity to cut the wireline and 1.5-inch coiled tubing, if the super safety valve is equipped with a cutter ball, by using a nitrogen dome charge or applying balance line pressure, the safety valve has capability of cutting coiled tubing in OD 2 inch and 0.125 inch wall thickness,


The Super Safety Valve is designed with a chemical injection port and controlled by two hydraulic lines The SSV is operated to close by spring force, but the tool has a nitrogen charge chamber to quicken the closing time, which make the super safety valve has the ability to cut wireline and coiled tubing without the addition of balance line pressure.

Application of the super safety valve

  • Oil well drill stem testing
  • Oil well coil tubing operations
  • Oil well kill operations
  • Downhole wireline operations
