A numerical study to evaluate the effectiveness of using seismic vibrations to improve oil recovery is reported. The effect of the characteristics of the seismic vibrations, such as displacement amplitude and frequency, are studied. The enhancement in oil recovery from a simple pore model subjected to constant inlet injection flow rates and seismic vibrations is investigated. It is observed that seismic recovery increases with an increase in displacement amplitude and vibration frequency. In addition, oil recovery is more pronounced with an increase in displacement amplitude than with an increase in vibration frequency. When the injection flow rates are higher, seismic recovery is more visible. The findings from this experimental visualization study had a satisfactory qualitative match with the numerical observations. It can be inferred that seismic stimulations would be a prominent candidate for improving oil recovery from reservoirs.
