Time - frequency analysis of seismic data using local attributes a
Time-frequency analysis is an important technology in seismic data processing and interpretation. To localize frequency content in time, we have developed a novel method for computing a time-frequency map for nonstationary signals using an iterative inversion framework. We calculated time-varying Fourier coefficients by solving a least-squares problem that uses regularized nonstationary regress...
متن کاملAnalysis of Low-Frequency Passive Seismic Attributes in Maroun Oil Field, Iran
Nowadays, viable and cost-effective methods play a vital role in hydrocarbon exploration up to the point that geoscientists cannot rule out the importance of the passive seismic method (PSM) in oil exploration operations. This method is based on seismic energy, which has a natural source. This study focuses on seismic energy anomaly of 1-6 Hz. Some researches show that spectral and polarization...
متن کاملTime-frequency analysis of seismic reflection signals
In this paper we show the implementation of bilinear time-frequency representations in the interpretation of seismic data. In seismic stratigraphy the reeection patterns in seismic data are interpreted in terms of subsurface stratiication and lithological properties. The time-frequency representation clearly elicits seismic reeection patterns and can thus provide useful information on subsurfac...
متن کاملTime - Frequency Analysis of Seismic Sequences 1
Re ection patterns play an important role in seismic sequence stratigraphy, therefore making their quantitative description essential for the construction and validation of sequence stratigraphic models from seismic data. The characteristics of a seismic re ection pattern can be elicited from the data by representing the data as a joint function of time and frequency. Developments in the eld of...
متن کاملtime-frequency based single-frequency seismic attribute
spectral decomposition is a powerful tool for analysis of seismic data. fourier transform determines the frequency contents of a signal. but for analysis of non-stationary signals, 1-d transform to frequency domain is not sufficient. in early years, transforming of seismic traces into time and frequency domain was done via windowed fourier transform, called a short time fourier transform (stft)...
