A system includes a rig control system for controlling rig equipment operable to perform drilling operations to drill a wellbore at a wellsite, wherein the rig equipment includes a drawworks for raising or lowering a drill string, a pressure control system for controlling a pressure control manifold fluidly connected with the wellbore, and a blowout preventer (BOP) control system for controlling BOP equipment. The BOP control system is communicatively connected with the rig control system and the pressure control system, receives rig data, pressure data, and flow rate data from sensors included in the rig control system and the pressure control system, displays information indicative of an influx of formation fluid based at least one of the pressure data and the flow rate data, and causes the BOP equipment to close about the drill string.

Communicating with blowout preventer control system

A system includes a rig control system for controlling rig equipment operable to perform drilling operations to drill a wellbore at a wellsite, and a blowout preventer (BOP) control system for controlling BOP equipment that is communicatively connected with the rig control system. The rig equipment includes a drawworks for conveying a drill string, at least one sensor operable to output rig data related to the rig equipment, and a rig control workstation to monitor and control the rig equipment. The BOP control system includes at least one sensor operable to output BOP data indicative of operational status of the BOP equipment. When the BOP data indicates that the BOP equipment is closed, the rig control system is operable to display on the rig control workstation information indicative of the BOP equipment being closed, and limit use of the rig control workstation to operate the drawworks.

Systems and methods for communicating with a blowout preventer (BOP) control system. An example system includes a pressure control system for controlling a pressure control manifold fluidly connected with the wellbore and a BOP control system for controlling BOP equipment. The pressure control system may include a sensor operable to output pressure data indicative of wellbore pressure. The BOP control system may include a sensor operable to output BOP data indicative of operational status of the BOP equipment and a BOP human-machine interface (HMI) usable by a human user to monitor and control the BOP equipment. The BOP control system may be communicatively connected with the pressure control system, receive the pressure data, and display, on the BOP HMI, information based on the pressure data.
