WellBoss’ (RIV) Reservoir Isolation Valve is a mechanical isolation system designed to act as a shutdown valve and flow control device. This valve may be set during or after primary well completion. This valve is used to stop reservoir flow during ESP replacement or workover, thus preventing fluid losses and reducing rig time.

RIV valve is compatible with lower and upper completion systems. The RIV reservoir control valve is opened after installation of the Activation Sealing Assembly Anchor (Stinger) and setting the tubing to the required depth. The valve is closed when the RIV Activation Assembly is removed from the stinger during ESP replacement or workover. When closed, the valve stops fluid flowing from the reservoir, thus preventing fluid losses. In its closed position the RIV is designed for a maximum differential pressure of 5,000 psi (344 bar) and maximum temperature of 135 Deg C (275 Deg F).
