Shear‐wave velocity estimation
SEG Technical Program Expanded Abstracts 1993, 1993Shear-wave velocity estimation from principally porosity, clay content and compressional velocity has been widely studied by different authors for different core samples. When comparing the results of the velocity estimated with those laws and the velocity measured on core or with sonic logs and seismic data, discrepancies are often seen.

Estimation of seabed shear-wave velocity profiles using shear-wave source data
The Journal of the Acoustical Society of America, 2013This paper estimates seabed shear-wave velocity profiles and their uncertainties using interface-wave dispersion curves extracted from data generated by a shear-wave source. The shear-wave source generated a seismic signature over a frequency range between 2 and 60 Hz and was polarized in both in-line and cross-line orientations. Low-frequency Scholte-

Shear wave velocity in surface sediments
Jökull, 2011Surface sediments of different nature are common in Iceland. Natural soil sites and man-made fillings commonly serve as foundations for different types of structures. In Civil engineering work it is fundamental to know the geotechnical properties of these materials in the upper 20–30 m.

Seafloor shear wave velocity variability.
The Journal of the Acoustical Society of America, 1992In gross classification, sediments of the deep seafloor may be of terrigenous or marine origin. Those of marine origin are classified as oozes (generally calcareous) or clays (generally siliceous) depending largely on whether their CaCO3 content is greater or less than 30%.

Surface Wave Inversion for Shear Wave Velocity
1991Land based seismic exploration has typically viewed the surface wave or ground roll as undesirable noise while earthquake seismology has been able to use the surface wave to invert for lateral variations in crust-upper mantle shear-wave velocity. Although surface-wave inversion techniques for shear-wave velocity and shear-wave Q are easy to apply once ...

Velocities of compressional and shear waves in limestones
Geophysical Prospecting, 2003Carbonate rocks are important hydrocarbon reservoir rocks with complex textures and petrophysical properties (porosity and permeability) mainly resulting from various diagenetic processes (compaction, dissolution, precipitation, cementation, etc.). These complexities make prediction of reservoir characteristics (e.g.

Shear Wave Velocity Profiling with Surface Wave Methods
Geotechnical Engineering State of the Art and Practice, 2012Surface wave method was introduced as a tool to the geotechnical and infrastructure engineering fields in the early 1980's. Since then, the method has been continuously modified and improved. The adoption of the method has accelerated in the last ten years because of the interest of the engineering community, and due to the development of affordable ...

Shear Wave Velocity in Marine Sediment
Japanese Journal of Applied Physics, 2006The shear wave velocity in surficial marine sediment is important evaluating the physical properties of such sediment. In this study, the dispersion of the shear wave velocity is investigated using the Biot–Stoll model. Next, the shear wave velocities of air- and water-saturated beach sands are measured at a low overburden stress, and the shear moduli ...

Shear Wave Velocities of Campanian Tuffs (Southern Italy)
1st EEGS Meeting, 1995Shear wave velocities of Campanian tuffs were measured both in the laboratory (ultrasonic pulse and resonant column) and in the field (Rayleigh wave spectral analysis). It resulted that it is not sufficient to recognize the tuff basement for computing the site amplification effects, but the dynamic parameters have to be measured because of hardening ...
