Abstract

See full text

A method of hierarchical pressure management for managed pressure drilling operations includes receiving a measured pressure value. If the measured pressure exceeds an MPD pressure set point, commanding one or more choke valves of an MPD choke manifold to open until the measured pressure is approximately equal to the MPD pressure set point or is commanded to a fully opened choke aperture setting. If at any time the measured pressure exceeds a pressure control valve set point, parking the MPD choke manifold and commanding one or more pressure control valve system valves to open until the measured pressure is less than the pressure control valve set point or is commanded to a fully opened pressure control valve setting. If at any time the measured pressure exceeds a pressure relief valve set point, commanding a pressure relief valve to open.
