Joint elastic full waveform inversion of multi-component geophone and distributed acoustic sensing data
A VSS-based joint FWI framework enables direct multi-deployment inversion of geophone and DAS data, yielding more accurate elastic parameter recovery than single-sensor cases on Marmousi benchmarks when sensors provide complementary information.
