Ground-penetrating radar (GPR) surveys, outcrop measurements, and cores provide a high resolution three-dimensional geologic model to investigate the effects of shales in marine-influenced lower delta-plain distributary channel deposits within the Cretaceous-age Ferron sandstone at Corbula Gulch in central Utah, USA. Shale statistics are computed from(More)
To decouple the parameters in elastic full-waveform inversion (FWI), we evaluated a new multistep-length gradient approach to assign individual weights separately for each parameter gradient and search for an optimal step length along the composite gradient direction. To perform wavefield extrapolations for the inversion, we used parallelized high-precision(More)
