This session focuses on advances in well construction and integrity that enhance safety, reliability, and cost efficiency across diverse operating environments. The presentations address data-driven optimization of well design to mitigate operational risks, integrity assurance during casing drilling supported by digital and AI-enabled tools, and the operational and economic benefits of advanced casing technologies in mature and complex fields. Case studies from onshore, shallow water, and pre-salt developments highlight the full lifecycle of well construction, from design and execution to long-term integrity management. Lessons learned from large-scale casing drilling campaigns provide practical insights into performance improvement, risk reduction, and standardization. Together, the papers demonstrate how integrated engineering, digitalization, and execution excellence are key enablers for resilient well construction strategies.
