However, improvement in sweep efficiency with alcohol-treated CO 2 is more pronounced at higher pressures, whereas improvement in displacement efficiency is more pronounced at lower pressures. It shows that alcohol-treated CO 2 improves CO 2 sweep efficiency. Simulation results reveal that alcohol-treated CO 2 injection is found superior to pure CO 2 injection in oil recovery (5–9%) and CO 2 storage efficiency (4–6%).
All simulations were run at constant temperature (70☌), whereas pressures were determined using a pressure-volume-temperature simulator for immiscible (1400 psi) and near-miscible (1780 psi) conditions. Alcohol-treated CO 2 consisted of a mixture of 4 wt% of ethanol and 96 wt% of CO 2.
A SPE-5 3D model was used to simulate oil recovery and CO 2 storage at field scale for two sets of fluid pairs: (1) pure CO 2 and decane and (2) alcohol-treated CO 2 and decane. was used to examine the effect of alcohol-treated CO 2 on the recovery mechanism. A compositional reservoir simulator from Computer Modelling Group Ltd. This extended abstract presents numerical studies to delineate the effect of alcohol-treated CO 2 injection on enhancing miscibility, CO 2 storage and oil recovery at immiscible and near-miscible conditions. In case of a depleted oil reservoir, reservoir pressure is not sufficient to achieve miscible or near-miscible condition. The innovative wave propagation models of Altair. Altair WinProp finds applications in a wide range of fields - from satellite to terrestrial and from rural via urban to indoor radio links. This is a very comprehensive suite of tools in the realm of wireless propagation and radio network planning. Oil recovery and CO 2 storage related to CO 2 enhance oil recovery are dependent on CO 2 miscibility. Wave Propagation and Radio Network Planning.
