This manuscript provides a comprehensive examination of cutting-edge drilling technologies and their implications for the energy industry. Managed Pressure Drilling (MPD) and Controlled Mud Level (CML) are meticulously dissected, uncovering their techniques, equipment, and operational intricacies. Additionally, Managed Pressure Cementing (MPC) is explored, showcasing the ingenious application of MPD during cementing operations. The chapter then ventures into the realm of digitalization and automation, highlighting the role of Wired Drill Pipe as a conduit for high-speed data transmission, transforming drilling through real-time monitoring and decision-making. The convergence of digitalization and automation with MPD and CML systems is unveiled, elucidating how these technologies can create semi or fully automated systems that optimize drilling processes, enhance accuracy, and reduce nonproductive time (NPT). This manuscript invites readers on a journey into the frontier of drilling technology, where innovation knows no bounds, and the future of energy exploration and production is being reshaped
