Field examples from the Western Desert of Egypt show the effectiveness of compressional-wave velocity (V p) and shear-wave velocity (V s) crossplots for identifying the type of fluid contained in a ...

Affiliazione: Università di Cagliari & Geological Survey of Denmark and Greenland Abstract: The analysis of surface wave dispersion curves is a way to infer the vertical distribution of shear-wave ...

A new approach to shear-wave data acquisition should lead to expanded use of shear waves in prospect evaluation and reservoir characterization. This technology not only allows shear-wave seismic data ...

Small seismic waves generated by urban activity in Mexico City offer a glimpse at how subsiding soils may be speeding up the seismic waves that travel in the shallow layers beneath the city. As ...
