abstract

  • In the oil and gas industry, it is very important to recover the maximum amount of oil extracted from the reservoirs. Many methods are employed in the extraction process in Enhanced Oil Recovery (EOR) to obtain maximum oil recovery, but unfortunately, only up to 70% can be recovered from the reservoirs. One of the most important and new techniques in EOR is the use of nanotechnology during the recovery process. Without mathematical analysis, it is difficult to perform experiments to recover oil, as the experimental setup is very costly. Hence, it is essential to study the physical properties of the reservoir and its flow behaviour to get maximum output. In this paper, we studied the impact of the physical behaviour of the oil reservoir and its characteristics in terms of oil flow by considering a hypothetical cubical oil reservoir. Our aim is to predict the maximum oil recovery under the influence of temperature (i.e., 20oC, 90oC, and 130oC) by using nanofluid flow and to investigate the impact of geometry on oil recovery. The ANSYS Fluent-based finite volume method is used for the simulation process. The results obtained from the mathematical analysis show that the impact of geometrical behaviour is very significant in improving oil recovery. It is also found that when the temperature of the reservoir increases, the oil recovery rate suddenly decreases, and maximum oil recovery is obtained at 90 degrees Celsius in all cases of the nanoparticles at different flow rates. In the future, we will extend this work to more complex geometries to predict maximum oil recovery under the influence of high temperature and pressure.
