Joint permeability inversions from both time-lapse seismic data and time-lapse well measurements. a Inversion result using PDE solvers. b The same as a but for the FNO surrogate. c The same as a but with the NF-based constraint. d The same as a but now for the FNO surrogate with the NF-based constraint. e–h The error of the permeability inversions in a-d, compared to the unseen ground truth shown in Fig. 6a. i The FNO prediction errors as a function of the number of iterations for b and d
