Published data of passive seismic, vibration impact on residual oil production as well as selected frequency effect in oil exploration reveal the important role of resonances. If the wave length is much larger than the heterogeneity scale, the resonance appears to be internal one and it has to be accounted for in kinetic part of the dynamics equations. The model is developed to find a general form of dispersion curve, corresponding to the medium resonance at so-called dominant frequencies. The resonance is understood here as a negative dissipation limited by nonlinear generation of higher frequency oscillations. It includes the flux of energy from the Goldstone mode of extremely long waves with neutral stability towards dominant wave spectrum of flickering frequencies. The variants of small ganglia oscillations with surface tension as a restoring force and of gas/oil bubbles under high pressure are compared.
