This book serves as a one-stop source for developing an enhanced understanding of these available methods, and specifically documents, analyses, and evaluates their suitability and robustness for depicting and characterizing the phenomenon of CO -reservoir oil miscibility in a fast and cost-effective manner. Such information can greatly assist a project team in selecting an appropriate MMP determination method as per the project’s need at a given project’s stage, be that screening, design, or implementation. will be of interest to petroleum science and engineering professionals, researchers, and undergraduate and graduate students engaged in CO enhanced oil recovery (EOR) and/or simultaneous CO -EOR and storage projects and related research. It may also be of interest to engineering and management professionals within the petroleum industry who have responsibility for implementing CO -EOR projects.
