Abstract
"Unconventional shale reservoirs are currently gaining significant interest due to the huge hydrocarbon volumes that they bear. Enhanced oil recovery (EOR) techniques have been suggested to increase recovery from shale reservoirs. One of the most promising EOR methods is gas EOR (GEOR), most notably carbon dioxide (CO2). Not only can CO2 increase oil recovery by interacting with the oil and the shale, but it has also been shown to adsorb to the shale rock and thus is effective in both EOR applications and also carbon storage purposes. This research aims to experimentally investigate several of the interactions that may impact CO2 injection in shale reservoirs in hopes of defining and quantifying the factors impacting these interactions and how these factors can contribute to an improvement in oil recovery from these reservoirs. This research begins by undergoing a review and data analysis on immiscible CO2 injection to investigate its injection methods, mechanisms, governing equations, and factors influencing its applicability. Following this, a mathematical simulation was undergone to investigate the different CO2 flow regimes that could occur during CO2 injection in shale reservoirs. The interaction of the CO2 with the shale rock via adsorption was investigated by undergoing several adsorption experiments. The CO2 interaction with the oil was also investigated by undergoing oil swelling which is considered the main mechanism by which oil recovery can be increased during immiscible CO2 injection, and asphaltene experiments to investigate the factors impacting these two interactions. Finally, cyclic CO2 injection was performed to determine the oil recovery potential of GEOR from shale reservoirs"--Abstract, page iv.
