Abstract
A managed Pressure Drilling manifold provides accurate back pressure control of a well head when drilling. The MPD system provides two paths for the drilling fluid to flow from the RCD to the flowline. The drilling fluid flows along an MPD path sending the drilling fluids through at least one sensor, preferably three sensors, a flow control device, and a flowmeter. The MPD system also provides a bypass path that isolates the flow control device and flowmeter while direct the drilling fluid from the RCD to the bypass to avoid the flow control device and flowmeter. The MPD system provides three valves that direct the drilling fluid in the bypass path or the MPD path.
