This session presents recent advances in drilling automation, real-time sensing, and fluid chemistry for challenging environments. The papers discuss integrated vibration monitoring systems for identifying abnormal downhole conditions, adaptive hybrid controllers combining conventional PID and machine learning methods, and the feasibility of Tesla turbine designs for inline rheology measurement. Field studies share practical solutions for drilling high-risk deviated wells, improving sand control, and optimizing liner running operations. Additional presentations address reliability-based casing design and corrosion prevention using environmentally safe inhibitors for HP/HT subsea systems. The session concludes with new cutter designs and lessons learned from the first salt cavern storage drilling campaign in the Middle East. Collectively, the work highlights how automation, sensing, and materials development are improving the safety and performance of modern drilling operations.
