Enhance Oil Recovery

Oil recovery and CO2 storage related to CO2 enhance oil recovery are dependent on CO2 miscibility. In case of a depleted oil reservoir, reservoir pressure is not sufficient to achieve miscible or near-miscible condition. This extended abstract presents numerical studies to delineate the effect of alcohol-treated CO2 injection on enhancing miscibility, CO2 storage and oil recovery at immiscible and near-miscible conditions. A compositional reservoir simulator from Computer Modelling Group Ltd. was used to examine the effect of alcohol-treated CO2 on the recovery mechanism. A SPE-5 3D model was used to simulate oil recovery and CO2 storage at field scale for two sets of fluid pairs: (1) pure CO2 and decane and (2) alcohol-treated CO2 and decane. Alcohol-treated CO2 consisted of a mixture of 4 wt% of ethanol and 96 wt% of CO2. All simulations were run at constant temperature (70°C), whereas pressures were determined using a pressure-volume-temperature simulator for immiscible (1400 psi) and near-miscible (1780 psi) conditions. Simulation results reveal that alcohol-treated CO2 injection is found superior to pure CO2 injection in oil recovery (5–9%) and CO2 storage efficiency (4–6%). It shows that alcohol-treated CO2 improves CO2 sweep efficiency. However, improvement in sweep efficiency with alcohol-treated CO2 is more pronounced at higher pressures, whereas improvement in displacement efficiency is more pronounced at lower pressures. The proposed methodology has potential to enhance the feasibility of CO2 sequestration in depleted oil reservoirs and improve both displacement and sweep efficiency of CO2.

Storage Potential

Storing carbon dioxide (CO2 ) in oil reservoirs as part of CO2 -based enhanced oil recovery (CO2 -EOR) can be a cost-effective solution to reduce emissions into the atmosphere. In this paper, we analyze the economics of this option in order to estimate the amount of CO2 that could be profitably stored in different regions of the world. We consider situations in which the CO2 -EOR operator either purchases the CO2 supplied or is paid for its storage. Building upon extensive data sets concerning the characteristics and location of oil reservoirs and emission sources, the paper focuses on opportunities outside North America. Using net present value (NPV) as an indicator for profitability, we conduct a break-even analysis to relate CO2 supply prices (positive or negative) to economically viable storage potential.
