Least-squares RTM of a seismic-while-drilling dataset
Nasser Kazemi, Daniel Trad, Kris Innanen +1
Least-squares migration can, in theory, reduce the acquisition footprint and improve the illumination of the subsurface structures. It can also recover the amplitudes of the events…
Statics Preserving Sparse Radon Transform
Nasser Kazemi
This paper develops a Statics Preserving Sparse Radon transform (SPSR) algorithm.The de-coloration power of Radon basis functions depends on different factors. The most important o…
Application of shifted-Laplace preconditioners for heterogenous Helmholtz equation- part 2: Full waveform inversion
Nasser Kazemi
Seismic waves bring information from the physical properties of the earth to the surface. Full waveform inversion (FWI) is a local optimization technique which tries to invert the…
Application of shifted-Laplace preconditioners for heterogenous Helmholtz equation- part 1: Data modelling
Nasser Kazemi
In several geophysical applications, such as full waveform inversion and data modelling, we are facing the solution of inhomogeneous Helmholtz equation. The difficulties of solving…
