The application of Prony's decomposition in the analysis of seismic signals
https://doi.org/10.18303/2619-1563-2024-4-75
Abstract
The article presents the results of Prony decomposition using real and synthetic data as an example. This decomposition allows us to obtain the following parameters of a seismic record: attenuation, amplitude, frequency, and phase. The attenuation parameter is associated with the characteristics of the rocks in the geological section, in particular, the compaction of the rocks. The results of the study demonstrate a high correlation between the quality factor, which is the inverse of the obtained attenuation value, and the density of the rocks in the section.
Supporting agencies: The study was carried out as part of government assignment to the Russian Academy of Sciences in basic research, Project FWZZ-2022-0017.
