Abstract: A well annulus pressure control system includes a reservoir in fluid communication with a well annulus, a control valve disposed on a fluid coupling between the reservoir and well annulus, a sensor disposed in the well annulus that detects a well annulus pressure, a controller that is operatively coupled to the control valve and sensor. The controller detects the well annulus pressure of the fluid in the well annulus based on sensor data from the sensor, controls the control valve to release the fluid from the well annulus into the reservoir in response to determining that the detected well annulus pressure is higher than a normal operating range of pressure in the well annulus, and controls the control valve to refill the fluid from the reservoir back into the well annulus in response to determining that the detected well annulus pressure is lower than the normal operating range.

Abstract: A method for completing a subterranean well with a smart completion system includes drilling the subterranean well to a first depth with a first drill string having a first drill string tubular and a first bottom hole assembly with a first drill bit. The first drill string is retrieved and a casing is cemented within the first depth. The subterranean well is drilled to a second depth with a second drill string having a second drill string tubular, a liner, and a second bottom hole assembly that includes a smart completion and a second drill bit. The liner is set within the casing and the second drill string tubular is retrieved, retaining the liner and the second bottom hole assembly within the subterranean well. Fluid from the subterranean well is produced through the second bottom hole assembly.
