The Precision Oiltools Formation Saver Valve is designed as a cost-effective solution for ESP completions, to protect the formation when the pump is switched off. Installed below the pump, the FSV is open when the pump is in operation and closes as soon as backflow activates the piloting mechanism. A lock open facility gives the option to carry out intervention operations below the FSV.
Installed in conjunction with ESP completions. When the ESP pump is off, backflow activates the FSV, preventing fluid loss into the formation and loss of fluid in the pump.
The valve will be a unidirectional barrier, holding pressure from above.
The valve will allow production from the well when ESP is turned ON
The FSV will automatically close itself as soon as the ESP is shut off
(differential pressure created across the valve). The valve has the feature of locking open so that intervention through the valve can happen.
good ideas made great
