Control System Functional Description • Devices that control the machines, that collect data from the rig and downhole sensors, and that are used by a human operators as interfaces to control the machines (HMI) and to get information from the drilling process. • Additional Scope: Autonomy of the Drilling Process
IADC ART Workshop Vienna June 2014 Control Systems Presenter: Calvin Inabinett
Controls mapping to DSA-R Vision • “well plans are uploaded into an interoperable drilling system”, • “updates remote operators and experts in real time” • “Routine multiple wells will rely on remote operations centers” IADC ART Workshop Vienna June 2014 Control Systems Presenter: Calvin Inabinett

Current Situation - Control Systems • Most Drilling Control Systems today are fully preprogrammed and act repeatedly based on defined input and known states. • Drilling control systems of today are designed around the human operator. • Human is a sensor • Human interprets sensor readouts and deciding actions.
• Automation is primarily through mechanization IADC ART Workshop Vienna June 2014 Control Systems Presenter: Calvin Inabinett
Current State of the Art • Bit/BHA Vibration detection and mitigation • Drilling optimization • Mathematical models or down-hole measurements for downhole conditions • ROP optimization (through improved WOB)
IADC ART Workshop Vienna June 2014 Control Systems Presenter: Calvin Inabinett
Barriers/Challenges
• New Technology is not the main barrier. It is the holistic approach to this which is the challenge. • Validation of the system. • Levels of automation • There is still a challenge to design a control system to manage the drilling process vs. managing drilling equipment. • Orchestration of different capabilities is a challenge. • Hard to implement multi-dimensional aspects of drilling • Algorithm challenge: Solve one-dimensional challenges i.e. Vibration, but still not Vibration + Pressure Management, where there are several existing (and sometimes conflicting) goals at the same time.
• Knowledge of how to determine the health and operating conditions of all system machines and equipment is needed to build control system intelligence. IADC ART Workshop Vienna June 2014 Control System Presenter: Calvin Inabinett

Way Ahead
• Extend Control Systems beyond mechanization into Automation • Autonomy depends on • Control equipment capability • Human interaction perspective
• Use Cases: The level of automation possible to achieve will depend on the understanding of all the nominal and off-nominal scenarios to be understood and factored into the system design • Environmental • Operational • Situational conditions IADC ART Workshop Vienna June 2014 Control System Presenter: Calvin Inabinett
