Abstract
A control system for controlling pressure of fluid within a wellbore includes a rotating control device (RCD), a distribution manifold, a choke and kill (CK) manifold, and a managed pressure drilling (MPD) manifold fluidly connected with each other, a sensor operable to facilitate fluid measurements indicative of a property of the fluid, and a controller communicatively connected with the distribution manifold and the sensor. The controller is operable to receive the fluid measurements, cause the distribution manifold to direct the fluid discharged out of the wellbore via the RCD to flow through the MPD manifold to thereby permit the MPD manifold to control the pressure of the fluid within the wellbore, and cause the distribution manifold to direct the fluid discharged out of the wellbore via the RCD to flow through the CK manifold to thereby permit the CK manifold to control the pressure of the fluid within the wellbore.
