The urgent need to combat climate change has encouraged the development of Carbon Capture and Storage (CCS) technologies to reduce greenhouse gas emissions from various industrial processes and energy production. The main function of using CCS is to capture Carbon dioxide (CO2) and store it in geological formations as much as possible permanently. Given that CCS involves gas injection, typically predominantly CO2, it is undeniable that there is the potential to inject a mixture of CO2, such as CH4, and other greenhouse gases that can further enhance the objective of CCS. In this study, CCS technology will be implemented in the "S" field, which is a depleted oil and gas reservoir site. Considering that the greenhouse gas by-products from the oil and gas industry include CO2 and CH4, this study aims to simulate the utilization of CCS technology using a mixture of injection gases composed of these two greenhouse gases. The inclusion of CH4 in the injection gas mixture is a pivotal aspect that needs to be considered in CCS application as CH4 has a global warming potential 28 times higher than that of CO2 [IPCC, 2014]. The simulation of CCS technology application will be carried out using CMG software and focus on seeing how much CO2 is trapped. Consequently, this study has the objective of investigating the impact of introducing CH4 into the gas injection on CO2 capture for each trapping mechanism in the "S" field.
