As coiled tubing drilling and through-tubing milling applications become more complex, operators and service companies are increasingly relying on digital technologies, automation, advanced tool designs, and data-driven workflows to improve performance. This session presents innovations in downhole sensing, high-frequency data acquisition, intelligent drilling systems, pressure management, milling optimization, and equipment reliability. Presenters will share lessons learned from field deployments that are enabling safer operations, improved decision-making, and expanded application envelopes across both conventional and emerging energy developments.
