Abstract:
A managed pressure drilling (MPD) system employs reliability models such as Failure Modes and Effects Analysis (FMEA), Fault Tree Analysis (FTA), Ishikawa diagram, Pareto chart, Reliability Block Diagram (RBD) in assessing and optimizing the system reliability. The MPD drilling system is suitable for offshore drilling operations.
