Determination of Informative Frequency Range in Seismic Noise in the Method of Remote Appraisal of Hydrocarbon Reservoirs

The article describes a solution to the problem connected with the earlier proposed method of remote appraisal of hydrocarbon reservoirs by passive seismic. It is shown that a linearity only appears in a certain frequency range and fails fast when the latter expands. It is found that the linearity is connected with the non-Gaussian behavior of seismic noise in the isolated specific frequency range. The author proposes a method to asses an informative frequency range using experimental data, polyspectral analysis and surrogate time series.
