Drilling operations are conducted on the drill floor by monitoring the surface drilling data from the drilling equipment. However, the surface drilling data does not provide direct evidence of the actual drilling conditions deep under the seafloor. Even so, using the surface drilling data is effective in providing information about these drilling conditions.
CDEX is developing some new systems for monitoring surface drilling data, calculating the forces exerted on the drill pipe, and analyzing drill pipe conditions as well as the drill bit, by integrating numerical simulations with surface drilling data. Information about the physical properties of the formation layer being drilled is beneficial, not only for efficient drilling operations, but also from a scientific research aspect. CDEX is developing a system to estimate the drilling properties of formation being drilled in real-time by simulation with surface drilling data. In addition, CDEX is developing an operation support system, including an anomaly detection system, based on AI technology using surface drilling data.
