Continuous along the Trace Measurements of Seismic Attenuation - Further Improvements, Synthetic and Field Data Tests

Accurate estimates of the seismic quality factor Q enable seismic images with a better resolution and a more correct positioning of events to be obtained. Also, Q can successfully be utilized for lithology discrimination and reservoir characterization. We introduce further improvements of our method for continuous in time measurements of seismic attenuation along the trace. The method operates in the time domain and enables the corruptive impact of the reflectivity to be compensated in a straightforward two-step way. The efficiency of the method is demonstrated with synthetic data from a finely layered attenuating medium and with field data from a productive area in Ukraine.
