Dr. Ilya Tsvankin, former CWP student Yanhua Liu (now at Shell), and their collaborators from INPEX have published a synthetic study for offshore seismic data that analyzes the potential of two types of optical fibers used in distributed acoustic sensing (DAS). They apply anisotropic elastic full-waveform inversion (FWI) and time-lapse elastic FWI to simulated seafloor data recorded with both straight and helically wound fibers (HWF). The results show that HWF with relatively small wrapping angles generally provide more accurate inverted medium parameters, especially if the offset range is limited. Check out their paper in The Leading Edge, which can be found here.
