Drill Stem Testing Tools SSC Valve 10000 psi WP Storm Valve For Well Testing


The Subsurface Control Valve Storm Valve is is a combination valve, aslo called Storm Valve, which is especially useful in offshore operations when storms are expected or when surface equipment, such as blowout preventers, must be repaired. Becasued the storm valve allows operators to close in a well that is being drilled without having to pull the workstring.

Normally a hookwall type packer, such as the RTTS Packer, is used with the Storm Valve to support the weight of the workstring. The packer seals inside the casing (surface pipe or intermediate casing string), and the SSC Valve seals the inside diameter of the workstring. Because the SSC Valve includes a back-off connection, the workstring above it can be removed and reconnected when operations resume

Benefit of Subsurface control valve

• The subsurface control valve can save rig time during operation.
• It is easy to operate the subsurface control valve.
• The subsurface control valve tests blowout preventers during drilling operations
• The subsurface control valve can increase the rig crew’s safety
