dc.description.abstract | In this study, the CO2 Huff and Puff method was investigated as a potential enhanced oil recovery technique. The CO2 Huff and Puff method is a promising enhanced oil recovery technique that utilizes carbon dioxide to improve sweep efficiency, mobility ratio and to reduce the oil viscosity that will enhance the oil production. In the modern world, more focus is being placed on the potential for CO2-EOR to enable geological CO2 storage because of the mounting demand to address climate change, which has elevated carbon capture to the forefront as a strategy for emission abatement. This method involves injecting CO2 into the reservoir, followed by a soaking period and a production phase, with the aim of improving the displacement of oil. The study utilized a reservoir simulation model on SMG software to evaluate the performance of the method, focusing on the impact of operational parameters such as number of cycles, injection rate, and soaking period on a tight reservoir with heavy oil. Results showed that increasing the number of cycles and injection rate improved oil production and recovery factor, with optimal values of 2 cycles for one base scenario and 3 cycles for the others, and an injection rate of 80 tons per day with incremental recovery of 15.98%. Additionally, a 30-day soaking period was found to be optimal for a particular reservoir with cumulative oil production of 81.95 MSTB and recovery factor of 22.52%. Overall, this study provides valuable insights for optimizing the application of the CO2 Huff and Puff method, contributing to the development of more efficient and sustainable oil recovery techniques. | en_US |
