Pressure-balanced drilling choke

The M-I SWACO AUTOCHOKE unit provides automatic, precise pressure control. It is the best choke technology available today for UBD and MPD applications. The AUTOCHOKE unit regulates casing pressure automatically under all conditions for a wide range of tasks: regulating mud pump start-up or shutdown, making and breaking drill-pipe connections, or allowing mud/gas flows alternately through the choke.
