Source footprint elimination in full-waveform inversion by model extension: Application to elastic guided waves recorded by distributed acoustic sensing in unconventional reservoir

Autor: Bader, Milad, Clapp, Robert G., Nihei, Kurt T., Biondi, Biondo

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 seismic sources and can be exacerbated by source-related errors in the model

Detection and characterization of microseismic events from fiber-optic DAS data using deep learning

Autor: Huot, Fantine, Lellouch, Ariel, Given, Paige, Luo, Bin, Clapp, Robert G., Nemeth, Tamas, Nihei, Kurt T., Biondi, Biondo L.

Microseismic analysis is a valuable tool for fracture characterization in the earth's subsurface. As distributed acoustic sensing (DAS) fibers are deployed at depth inside wells, they hold vast potential for high-resolution microseismic analysis. How
