Abstract

Rising CO2 concentrations in the atmosphere have become a critical global challenge, mainly due to its significant role in climate change and global warming. Increasing CO? emissions from industrial activities and fossil fuel combustion intensify the greenhouse effect, leading to higher global average temperatures, extreme weather events, and widespread environmental damage. As a potential mitigation strategy, CO? injection into subsurface reservoirs has gained attention, not only as a means for carbon sequestration but also for enhanced oil recovery (EOR). To optimize this process, forecasting plays an important role in evaluating the expected oil and gas production after CO? injection. This study focuses on the continuous injection of CO? in the KL Field, which consists of two injection wells and three production wells. The objective was to determine the optimal continuous CO? injection flow rate that would result in maximum CO? storage. Using tNavigator software, the analysis covers an operational period of 26 years, from April 2024 to April 2050, and the results show that an injection flow rate of 9.5 MMSCF per day for each injection well is the optimal scenario. This scenario allows the storage of 6.29 billion tons of CO?, derived from a total injection volume of 10.49 billion tons. Simultaneously, this scenario achieves oil recovery of 15.72 MMSTB.
