Three-dimensional seismic characterization and imaging of the Soda Lake geothermal field
Kai Gao, Lianjie Huang, Trenton Cladouhos
Accurate characterization of subsurface geophysical properties and detection of the fault system are essential for geothermal energy exploration and production. The Soda Lake geoth…
A hybrid eikonal solver for accurate first-arrival traveltime computation in anisotropic media with strong contrasts
Kai Gao, Lianjie Huang
First-arrival traveltime computation is crucial for many applications such as traveltime tomography, Kirchhoff migration, etc. There exist two major issues in conventional eikonal…
Acoustic- and elastic-waveform inversion with total generalized p-variation regularization
Kai Gao, Lianjie Huang
Geophysical models usually contain both sharp interfaces and smooth variations, and it is difficult to accurately account for both of these two types of medium parameter variations…
Optimal damping ratios of multi-axial perfectly matched layers for elastic-wave modeling in general anisotropic media
Kai Gao, Lianjie Huang
The conventional Perfectly Matched Layer (PML) is unstable for certain kinds of anisotropic media. This instability is intrinsic and independent of PML formulation or implementatio…
