A Novel Method for Q Estimation Based on the Generalized Logarithmic Spectral Ratio

The accuracy of Q factor estimation has an immediate impact on seismic data compensation and resolution enhancement. Among the Q estimation methods, the logarithmic spectral ratio is of high accuracy, but with weak anti-noise property. By contrast, the logarithmic spectral area-difference method owns better noise immunity. In this abstract, we propose a novel Q estimation approach based on generalized logarithmic spectral ratio, through the discussion between the difference and relation of the above two methods. Test of synthetic model and real data demonstrate that the proposed approach, combining the advantages of logarithmic spectral ratio and logarithmic spectral area-difference methods, is able to estimate Q factor with high accuracy and anti-noise property.
