The period foregrounded data-driven drilling through log-based geopressure estimation, enabling rapid assessment of abnormal pressures and safer mud-weight planning. It also unified offshore drilling efforts with on-site data analysis, fostering real-time decision making and improved site selection. Mud design innovations and regression-based optimization contributed to more stable wellbores and efficient drilling. Historical Significance: This era established the data-centric geomechanics paradigm that integrated logging, repeatable regression methods, and coredrilling workflows into offshore practice, laying the groundwork for modern drilling analytics and offshore technology development.
