A practical workflow for land seismic wavefield recovery with weighted matrix factorization
Yijun Zhang, Felix J. Herrmann
While wavefield reconstruction through weighted low-rank matrix factorizations has been shown to perform well on marine data, out-of-the-box application of this technology to land…

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…
