Interest in computational methods for calculating wave scattering from fractured geological
clusters is due to their application in processing and interpreting the data obtained during …

Accurately injecting and extrapolating multicomponent seismic data is a major step in elastic
reverse time migration (RTM) and full-waveform inversion. The theoretical basis of this …

Many modelling studies of wave scattering require repeated numerical simulations through
models with properties that differ only in a small sub-domain. Hence, it is of interest to …

The classical finite-difference (FD) method stimulates wave propagation in uniform grids. In
models with considerable velocity variations, the computational efficiency is compromised …

Full waveform inversion is a high-resolution subsurface imaging technique, in which full
seismic waveforms are used to infer subsurface physical properties. We present a novel …

In many inverse problems such as Full-Waveform Inversion (FWI) or reverse-time migration
(RTM) the key computational cost is the repeated seismic modeling. Due to data and model …

Summary Memorial University of Newfoundland and Labrador offers a comprehensive
education in geophysics and the broadest range of academic geophysical research …

We present a new target-enclosing full-waveform inversion method based on a new
objective function. This objective function is based on the mismatch between wavefields …

In exploration geophysics, we usually implement non-invasive methods to image the interior
of the Earth. Seismic methods, for example, are ideal for this purpose because they provide …
