HIRIDE Hopper | Schlumberger

How It Works. The flow exits the downstream side of the MPD nozzle at high velocity into a void space. The mixing hopper or other flowline opens into this void space via a manual butterfly valve. With the valve open, the high-velocity flow creates a zone of relative low pressure, which creates suction, drawing the material into the void space.
