Paper presented at the SEG International Exposition and Annual Meeting, September 15–20, 2019
Paper Number: SEG-2019-3216322
... ABSTRACT Seismic history matching is typically a high-dimensional and severely non-linear inverse problem, which is extremely time-consuming especially for ensemble-based methods. In this work, we propose a deep convolutional auto-encoder (DCAE) to sparsely represent the seismic data...
