Functions of A Blowout Preventer Control System:
Confine well fluid to the wellbore;
Provide means to add fluid to the wellbore;
Allow controlled volumes of fluid to be withdrawn from the wellbore.
Additionally, and in performing those primary functions, blowout preventer systems are used to:
Regulate and monitor wellbore pressure;
Center and hang off the drill string in the wellbore;
Shut in the well (e.g. seal the void, annulus, between drillpipe and casing);
Prevent the flow of formation fluid, influx, from the reservoir into the wellbore
Seal the wellhead (close off the wellbore);
Sever the casing or drill pipe (in case of emergencies).
