“…The results obtained from the analysis of the field data are comparable to the results of laboratory studies [9]. That is, a 60.54% increase in oil production was obtained when using intermittent longitudinal waves, an increase of 63.53% was obtained when using constant longitudinal waves, and an increase of 64.76% was obtained when using circular waves.…”

“…An optimal frequency of 10 Hz has been proposed to increase the permeability. Louhenapessy et al [9] reported that compared to longitudinal waves, circular waves increase the oil recovery by 3% more and reduce the residual oil saturation of oil rocks. The optimal frequency for circular waves is 20 Hz, and that for longitudinal waves is 35 Hz.…”

A set of techniques for well treatment aimed to enhance oil recovery are considered in the present study. These are based on the application of elastic waves of various types (dilation-wave, vibro-wave, or other acoustically induced effects). In such a context, a new technique is proposed to predict the effectiveness of the elastic-wave well treatment using the rank distribution according to Zipf 's law. It is revealed that, when the results of elastic wave well treatments are analyzed, groups of wells exploiting various geological deposits can differ in terms of their slope coefficients and free members. As the slope coefficient increases, the average increase in the well oil production rate (after the well treatment) becomes larger. An equation is obtained accordingly for estimating the slope coefficient in the Zipf 's equation from the frequency of the elastic wave. The obtained results demonstrate the applicability of the Zipf 's law in the analysis of the technological efficiency of elastic-wave well treatment methods.

When elastic waves act on rocks, the structure of the void space changes. The nucleation and formation of new cracks is possible. Wave action technologies are divided into two groups: with a frequency of less than 100 Hz and a frequency of more than 1 kHz. In the intermediate zone, no completed works and studies of wave action were found. The paper studies the results of the impact of elastic waves with different frequencies and amplitudes on oil production. With low-frequency exposure, an increase in permeability values is noted to a greater extent due to the appearance of new and an increase in the size of existing cracks. With high-frequency exposure, the viscosity of reservoir oil is greatly reduced. The greater the value of the initial viscosity, the more intense it decreases when exposed to highfrequency waves. For the Perm Territory, a comparison was made of the results of wave processing of production wells depending on the frequency of exposure. As the impact frequency increases, the average oil recovery after wave treatment decreases. With an increase in the frequency of exposure, the duration of operation of a well with increased oil production after wave treatment decreases. Models have been obtained to predict the time of operation of wells with additional oil production, additional oil production and an increase in oil production rate of wells after wave action. As a result, it can be noted that the most effective technologies are those with a lower frequency, but a large amplitude of exposure.

“…Residual oil is mobilized by applying compressional (P) wave excitation, which uses low-frequency and high-energy elastic waves [13,14,22]. In seismic wave-based EOR, wave sources (emitters) such as downhole/wellbore seismic vibrators, wellbore hydraulic pumps, and Vibroseismic technologies are frequently utilized for field implementation [13,16,17,24]. Elastic waves can be produced by the above-mentioned sources, either directly or indirectly.…”

Elastic wave-based oil mobilization of residual oil in heterogeneous reservoirs is a viable, low-cost, and green technology method of enhanced oil recovery (EOR). Applications for elastic (seismic) waves at the reservoir scale are currently in the preliminary stages of investigation and development. We employ a two-layer numerical finite element method (FEM) in this research to investigate the possibility of effective propagation of seismic waves in the low permeability area of a mature oil reservoir when seismic stress load is delivered to the rock matrix via a downhole source. The purpose of this research is to evaluate the potential of fluid and rock matrix displacement amplitudes for crossflow generation in a mature oil reservoir. In a low permeability formation, the numerical results reveal that, as the observation radius approaches the reservoir boundary, the rock matrix time-domain displacement performs better as a wave propagation parameter than the pore fluid displacement. However, crossflow oscillations at a peak mesoscopic frequency of 3.0 Hz produce an instantaneous oil transfer rate (recovery rate) of 2.5% (bypassed oil) from the low permeability area. This method can be used in combination with water flooding to recover more oil from both high and low-permeability areas. Mesoscopic attenuation frequency can therefore be utilized as one of the indicators to assess oil recovery in heterogeneous oil reservoirs.
