Analysis of acoustic impact on the formation by the method of filtration pressure waves

Abstract

© Engineering and Mining Geophysics 2020. Acoustic impact on the reservoir is a promising and environmentally friendly method of enhanced oil recovery. The positive effect of this effect is to increase the permeability of the reservoir and lowering the viscosity of the oil. The paper considers the method of filtration pressure waves to assess the effectiveness of acoustic impact. Numerical modeling showed that in the self-listening mode the effect of elastic waves will indicate an increase in the amplitude of pressure fluctuations. In the hydraulic listening mode, an indicator of the effectiveness of acoustic exposure is an increase in amplitude and a change in phase shift in the filtering pressure wave.
