Abstract

A computerized control system performs controlled pressure drilling in a formation with a drilling system according to a plan. A setup of at least the plan, the formation, and the drilling system is configured in the control system, and the setup is integrated with the drilling system. Functioning of the set up can then be conducted using one of a plurality of control modes, including an operating mode and a simulating mode. The control system functions the setup according to the operating mode for operational interaction with the setup using the integration of the setup with the drilling system. The control system can switch from the operating mode to the simulating mode for simulated interaction with the setup. The control system simulates for at least a time period the functioning of the setup according to the simulating mode using the integration of the setup with the drilling system. Current operations continue as at least one simulated operation or event is projected in the future. Ultimately, results from the simulating mode can be used in the operating mode as further operations continue.
