Analyzing the time-frequency features of seismic traces plays an important role in seismic stratigraphy analysis and hydrocarbon detection. The spectral decomposition algorithms can be categorized into (1) simple projection methods and (2) computationally intensive least-squares approaches. This special section is devoted to illustrate new time-frequency analysis algorithms and their application in geobodies and hydrocarbon detection.

Cheng et al. study the performance of an improved S transform with an asymmetric bi-Gaussian window. The asymmetric bi-Gaussian window can obtain an increased time resolution in the front direction, which can make event picking high-resolution and will facilitate an improved time-frequency characterization for oil...
