Miscible flooding is an effective tertiary Enhanced Oil Recovery technique after primary and secondary recovery methods have been exhausted. Minimum Miscibility Pressure (MMP) is the pressure at which miscibility is achieved between injected gas and reservoir oil. The main focus of this project is the design and implementation of a Rising Bubble Apparatus (RBA) for MMP identification. Core-flood and Vanishing Interfacial Tension (VIT) results are also analyzed and compared with RBA results, and a recommendation for MMP is made.
