In this research, numerical simulation was used to analyze the recovery factor during the CO2 displacement and storage phases in an Ecuadorian field. CO2 continuous injection and WAG methods were used. The methodology included field data collection, creation of a static reservoir model, configuration of the PVT model, construction of a dynamic model in GEM-CMG, and evaluation of CO2 injection scenarios. After a screening analysis, the optimal scenario was identified and the behavior of the recovery factor over time was studied. The simulation results indicate that the recovery factor with continuous injection was 28%, while with the WAG method, it reached 31%. It was concluded that the most efficient method was the WAG. Regarding storage, it was observed that continuous injection managed to store 83% of the CO2 in the reservoir. This is essential since it helps mitigate global warming by reducing CO2 emissions into the atmosphere.
