Finite-difference seismic wave modeling including surface topography
I present synthetics of seismic wave propagation near free surface topography. The velocity-stress formulations of both the full elastic and viscoelastic wave equations are used, and I have derived exact boundary conditions ...
A new approach to traveltime selection for Kirchoff migration
Prestack migration of seismic data is a dominant tool for imaging hydrocarbon bearing structures in the Earth. The standard prestack depth migration is a Kirchhoff approach using single-valued traveltimes computed from ...
Characterizing shallow aquifers with wave-propagation based geophysical methods: Imaging and attribute analysis
As the results of seismic reflection and ground penetrating radar (GPR) studies become more prevalent as input for quantitative groundwater and engineering studies, it is important to evaluate traditional approaches to ...
