Analysis of Enhance Oil Recovery Methods, A Comparative Approach to Determine the Suitable Eor Method for an Experimental Reservoir

This study presents a comparison of three Enhanced Oil Recovery (EOR) methods—Surfactant/Polymer (SP) EOR, Hot Water Injection EOR, and CO 2 Gas Injection EOR—to identify the most suitable technique for application in an experimental reservoir using simulated data of the reservoir. The methods were evaluated based on key performance indicators, including cumulative oil and water production, oil recovery factor, and water cut. The results demonstrate that Surfactant/Polymer EOR achieves the highest cumulative oil production (0.047815 MMSTB) and oil recovery factor (92.2909%), making it the most effective method for maximizing oil extraction. However, this method also produces a higher volume of water, necessitating robust water management strategies. Hot Water Injection EOR, while effective in heavy oil reservoirs, yielded the lowest oil production (0.0269035 MMSTB) but minimized water production. CO 2 Gas Injection EOR provided a balanced performance with moderate oil recovery and higher water production. Based on the comparative analysis of the simulation results, Surfactant/Polymer EOR is recommended as the most suitable recovery method for the experimental reservoir due to its outstanding oil recovery potential and overall production performance. Nevertheless, successful implementation of this method would require proper planning and management of the increased water production to optimize operational efficiency and economic viability
