Storm Choke
Subsurface safety valve
The Storm Choke is a subsurface safety valve designed to automatically shut off well production in the event of uncontrolled flow or surface equipment failure
The Storm Choke is a subsurface safety valve designed to automatically shut off well production in the event of uncontrolled flow or surface equipment failure
Installed in the tubing string, it operates as a velocity-sensitive valve that closes when the flow rate exceeds a preset limit, preventing uncontrolled production and protecting surface facilities from potential damage.
During normal operation, a calibrated spring mechanism holds the valve open until the flow rate — and thus the pressure differential across the choke — exceeds the predetermined threshold. If this limit is reached, the valve automatically closes, shutting in the well and ensuring immediate flow control.
