Wavefield recovery with limited-subspace weighted matrix factorizations
Yijun Zhang, Shashin Sharan, Oscar Lopez +1
Modern-day seismic imaging and monitoring technology increasingly rely on dense full-azimuth sampling. Unfortunately, the costs of acquiring densely sampled data rapidly become pro…
Total-variation regularization strategies in full-waveform inversion
Ernie Esser, Lluis Guasch, Tristan van Leeuwen +2
We propose an extended full-waveform inversion formulation that includes general convex constraints on the model. Though the full problem is highly nonconvex, the overarching optim…
Beating level-set methods for 3D seismic data interpolation: a primal-dual alternating approach
Rajiv Kumar, Oscar López, Damek Davis +2
Acquisition cost is a crucial bottleneck for seismic workflows, and low-rank formulations for data interpolation allow practitioners to `fill in' data volumes from critically subsa…
A penalty method for PDE-constrained optimization in inverse problems
Tristan van Leeuwen, Felix J. Herrmann
Many inverse and parameter estimation problems can be written as PDE-constrained optimization problems. The goal, then, is to infer the parameters, typically coefficients of the PD…
