Fail-safe closure in an emergency

Close up of the downhole tester valves.

A surface-operated hydraulic safety valve is necessary for applying fail-safe closure of the test string during testing operations.

Whether the emergency requiring a quick shutdown response is overpressure, equipment failure, or a downstream leak, having a surface safety valve (SSV) installed in the BOP stack of a jackup or land rig increases operational safety while reducing environmental risk.
