Integrated Drilling Control System

A method of performing controlled pressure drilling in a formation with a drilling system according to a plan, the method comprising:

• configuring, with a computerized control system, a setup of at least the plan, the formation, and the drilling system;
• integrating the setup of the computerized control system with the drilling system;
• indicating, at the computerized control system, a selection of one of a plurality of control modes for interacting with the setup, the control modes at least including (i) an operating mode for operational interaction with the setup and (ii) a simulating mode for simulated interaction with the setup;
• indicating, at the computerized control system, a selection of one of a plurality of operations for operating the setup;
• and
• functioning the setup with the computerized control system according to the selected operation within the selected control mode.

A computerized control system for a drilling system that performs controlled pressure drilling in a formation according to a plan, the system comprising:

• storage storing information pertaining at least to the formation, the drilling system, and the plan;
• communication equipment in communication with the drilling system;
• and
• processing equipment in communication with the storage and the communication equipment, the processing equipment configured to:
• configure a setup of at least the plan, the formation, and the drilling system;
• integrate the setup with the drilling system;
• function the setup according to an operating mode for operational interaction with the setup using the integration of the setup with the drilling system;
• switch from the operating mode to a simulating mode for simulated interaction with the setup;
• and
• simulating for a time period the functioning of the setup according to the simulation mode using the integration of the setup with the drilling system.
