SUBSEA PRESSURE CONTROL SYSTEM

A subsea pressure control system can include at least one subsea choke which variably restricts flow of drilling fluid from a well annulus to a surface location, the choke being positioned at a subsea location, and a subsea process control system which automatically operates the subsea choke, whereb...

Zusammenfassung:	A subsea pressure control system can include at least one subsea choke which variably restricts flow of drilling fluid from a well annulus to a surface location, the choke being positioned at a subsea location, and a subsea process control system which automatically operates the subsea choke, whereby a desired pressure is maintained in the well annulus. Another subsea pressure control system can include at least one subsea choke which variably restricts flow of drilling fluid from a well annulus to a surface location, the choke being positioned at a subsea location, and a subsea pump which pumps the drilling fluid from the subsea location to the surface location.
