This session delves into the cutting-edge research and practical innovations shaping our understanding of reservoir dynamics in carbon capture, utilization, and storage (CCUS). Presentations will explore multiscale investigations of wettability impacts, providing crucial insights into fluid behavior within complex reservoir systems. Attendees will also gain practical guidelines for CO2 mixture modeling to enhance predictive accuracy and efficiency. A novel FTIR-based workflow for quantifying CO2 adsorption and geochemical interactions will be unveiled, highlighting its potential to improve reservoir characterization. Further topics include basin-scale management strategies for CO2 storage, addressing key challenges such as dry-out effects and salt precipitation. The session will also examine the role of advanced techniques in enhancing CO2 miscibility for heavy oil recovery (EOR), along with strategies for monitoring pressure and assessing transient injection performance. Additionally, innovative hybrid methods aimed at minimizing CO2 emissions will be discussed, offering a comprehensive view of state-of-the-art practices and future directions in CCUS reservoir management. This session is an essential platform for technical professionals seeking to deepen their expertise in this evolving field.
