dc.description.abstractCarbon dioxide (CO₂), the main component of greenhouse gases, is released into the atmosphere primarily by combustion of fossil fuels like coal and oil. Due to a conspicuous lack of any CO₂ sequestration studies for Alaskan North Slope (ANS), the study of CO₂ sequestration options will open new avenues for CO₂ disposal options, such as viscous oil reservoirs and coal seams, on the ANS. This study focuses on the investigation of CO₂ storage options by screening ANS oil pools amenable to enhanced oil recovery, evaluating phase behavior of viscous oil and CO₂ mixture, and simulating enhanced oil recovery by CO₂ flooding, and migration of CO₂ in saline aquifer. Phase behavior studies revealed that CO₂ gas was partially miscible with West Sak, at the pressure closer to the reservoir pressure. Compositional simulation of CO₂ flooding for a five-spot West Sak reservoir pattern showed an increase in percent recovery with an increase in pore volume injected, but at the expense of an early breakthrough. Sensitivity analysis of CO₂ flooding project was found to be strongly dependent on the variables such as oil price and discount rate. Investigation of supercritical CO₂ injection in saline formation didn't increase temperature in the permafrost region.en_US
