Patent abstract
A pressure management device (PMD) for direct connection to a blowout preventor stack of a managed pressure drilling system, the PMD comprising a housing, one or more chokes, and a directional valve. The directional valve has a choke position and a bypass position. When the directional valve is in the choke position, the PMD operates to divert fluid entering the housing to one or more of the chokes. When the directional valve is in the bypass position, the PMD operates to divert fluid entering the housing to bypass the chokes. The inlet and outlet of each choke may be controlled by a dual shutoff valve, to selectively permit and restrict fluid flow through each choke.
