The method of filtration pressure waves to identify the heterogeneity of reservoir properties

Abstract

The impact on the reservoir with sound vibrations leads to a local change in its filtration properties. The permeability of the formation near the well with a working oscillator increases, the viscosity of the oil decreases. In this paper, the process of propagation of filtration pressure waves in such a reservoir is considered. Calculation of the amplitudes and phases of such hydrodynamic waves makes it possible to identify the location of zones of heterogeneity in the reservoir. The method of filtration pressure waves can be used to assess the effectiveness of acoustic stimulation of the formation.
