Storm Valve / Subsurface Safety Valve For Well Testing & Well Completion Service
The Subsurface Control Valve (SSC),also called Storm Valve is a combination valve and backoff joint that allows operators to close in a well that is being drilled without having to pull the workstring. This capability is especially useful in offshore operations when storms are expected or when surface equipment, such as blowout preventers, must be repaired. The valve eliminates the hazard of leaving pipe standing in the derrick during a storm.
