Proven for use in common MPD applications and land drilling operations.
The MPowerD™ 1500S managed pressure drilling (MPD) system is a fit-for-purpose system, combining a complete set of MPD automated features with the field-proven experience of NOV's HXE Hydraulic Choke. Our choke manifold and control system have shown use in many MPD applications and is most suitable for land drilling operations.
Our 1500S system features robust designs and includes proven subcomponents:
- Reversible gate and seat designed to direct high-velocity wear away from the positive sealing surface to extend choke life and reduce cost of ownership
- Customizable: Offers manual, hydraulic, or servo-driven actuator options and features 3-in. max orifice size (can be converted in the field to 2-in. or 1½-in. orifice)
Ruggedized, simple control systems
- Setpoint PLC local control panel monitors key drilling parameters such as pump strokes, standpipe pressure, wellhead pressure, and choke position simultaneously and continuously without fatigue
- Setpoint PLC local control panel automatically adjusts the choke as needed to maintain optimal annular pressure
