Previous EOR laboratory experiments and simulation studies in the literature illustrated promising results in terms of recovery factor for different EOR applications, such as CO 2 , surfactant, and natural gas. However, pilot tests performance reported contrast behavior due to...

... Reservoir Fluid In this study, four recovery schemes were investigated: Natural depletion, Immiscible Nitrogen (N 2 ) flood, Miscible Carbon Dioxide (CO 2 ) flood, and Huff n Puff CO 2 injection. In a previous study ( Joslin et. al., 2017 ), the authors had investigated the use of water flooding...

...: Many shales contain significant amounts of carbonates within the rock matrix. CO 2 is partially soluble in formation water, and when mixed with water forms a weak carbonic acid (H 2 CO 3 ). This may set up conditions where CO 2 reactivity with the carbonate causes some dissolution of rock, increasing...

... reservoirs are good candidates for enhanced recovery methods, since it has the potential to produce hydrocarbons, as well as storing CO 2 during injection and contributing to carbon footprint reduction ( Orr Jr., 2009a and 2009b ). CO 2 injection in these reservoirs are advantageous because of enhanced...

... compositions and phases of the volatile oil are very sensitive as the well starts producing. The second reason is the study of CO 2 EOR later requires the simulator's ability to represent the process of multiple contact miscibility between CO2 and oil appropriately.

Based on these results, we speculate that either the differences in pore throat size or the potential for kerogen content in the shales (or both characteristics) could explain the much slower oil recovery rates for the shales as compared to the Middle Bakken and Three Forks during CO 2 exposure...
