Time-Frequency Analysis of Seismic Signals

Time-frequency analysis of seismic signals is used to reveal the local properties of nonstationary signals, which vary with time and geologic depth. This book categorises time-frequency analysis methods into Gabor transform-type methods and energy density distribution methods and provides a practical guide to geophysicists for generating geophysically meaningful time-frequency spectra, processing seismic data with time-dependent operations, and exploiting the time-frequency space seismic attributes for quantitative characterisation of hydrocarbon reservoirs.

Time-frequency analysis is a powerful tool for studying seismic signals, as it allows us to reveal the local properties of nonstationary signals. These properties, such as time-period, frequency, and spectral content, vary with time, and the time of a seismic signal is a proxy for geologic depth. Therefore, the time-frequency spectrum is composed of the frequency spectra generated by using the classic Fourier transform at different time positions.

There are different methods for performing time-frequency analysis, and this book categorizes them into two groups: Gabor transform-type methods and energy density distribution methods. The Gabor transform is a type of time-frequency analysis that involves decomposing a signal into its constituent frequencies and then reconstructing it using a set of Gabor functions. The energy density distribution method is another approach that involves mapping the energy of a signal onto a two-dimensional plane.

This book provides a comprehensive and systematic presentation of time-frequency analysis methods, including technologies that have not been previously discussed in print. It emphasizes the fundamental theory and mathematical concepts behind each method, with an emphasis on the engineering aspects. The book also provides a practical guide to geophysicists who are attempting to generate geophysically meaningful time-frequency spectra, process seismic data with time-dependent operations, and exploit the time-frequency space seismic attributes for quantitative characterisation of hydrocarbon reservoirs.

In conclusion, time-frequency analysis is a crucial tool for studying seismic signals, and this book provides a comprehensive and practical guide to the methods and technologies involved. It is an essential resource for geophysicists, researchers, and engineers working in the field of seismology and petroleum engineering.
