Relationships between compressional‐wave and shear‐wave velocities in clastic silicate rocks
TL;DR: In this article, the authors analyzed new velocity data in addition to literature data derived from sonic log, seismic, and laboratory measurements for clastic silicate rocks and demonstrated simple systematic relationships between compressional and shear wave velocities.

PatentDOI
Instantaneous spectral analysis
TL;DR: In this paper, a method of seismic data processing is described in which a particular wavelet is selected from a plurality of wavelets as being most characteristic of a received seismic signal.
Journal ArticleDOI
Spectral decomposition of seismic data with continuous-wavelet transform
TL;DR: In this paper, the authors presented a new methodology for computing a time-frequency map for nonstationary signals using the continuous-wavelet transform (CWT), which does not require preselecting a window length and does not have a fixed timefrequency resolution over the timefrequency space.
Journal ArticleDOI
Shear-wave velocity estimation in porous rocks: theoretical formulation, preliminary verification and applications
M. L. Greenberg,John P. Castagna +1 more
TL;DR: In this paper, the authors developed a general method to predict shear-wave velocity in porous rocks, which depends on robust relationships between compressional- and shearwave velocities for water-saturated, pure, porous lithologies, and nearly linear mixing laws for solid rock constituents.
