Constrained non-linear AVO inversion based on the adjoint-state optimization
Ahmed, Nisar; Weibull, Wiktor Waldemar (Peer reviewed; Journal article, 2022)Pre-stack AVO inversion of seismic data is a modeling tool for estimating subsurface elastic properties. Our focus is on the model-based inversion method where then unknown variables are estimated by minimizing the misfit ... -
Frequency-dependent AVO inversion applied to physically based models for seismic attenuation
Ahmed, Nisar; Weibull, Wiktor Waldemar; Quintal, Beatriz; Grana, Dario; Bhakta, Tuhin (Peer reviewed; Journal article, 2022)Seismic inversion of amplitude versus offset (AVO) data in viscoelastic media can potentially provide high-resolution subsurface models of seismic velocities and attenuation from offset/angle seismic gathers. P- and S-wave ...
