Abstract
Post-stack acoustic impedance inversion is a band-limited and ill-posed inverse problem in which data-driven predictors may produce impedance models that are geologically plausible but inconsistent with the observations. This paper presents adjoint-guided Physics-Constrained Diffusion Inversion (PCD...
