Superstep wavefield propagation
Tamas Nemeth, Kurt Nihei, Alex Loddoch +10
This paper describes how to propagate wavefields for arbitrary numbers of traditional time steps in a single step, called a superstep. We show how to construct operators that accom…
Source footprint elimination in full-waveform inversion by model extension: Application to elastic guided waves recorded by distributed acoustic sensing in unconventional reservoir
Milad Bader, Robert G. Clapp, Kurt T. Nihei +1
Source footprints represent an inherent problem to full-waveform inversion (FWI). They are caused by the high data sensitivity to the model parameters in the vicinity of the seismi…
Moment tensor inversion of perforation shots using distributed acoustic sensing
Milad Bader, Robert G. Clapp, Kurt T. Nihei +1
Distributed acoustic sensing (DAS) fibers have enabled various geophysical applications in unconventional reservoirs. Combined with perforation shots, a DAS fiber can record valuab…
