PGS, a leading marine geophysical company, is running machine learning algorithms on its Cray XC40™ supercomputer, nicknamed "Abel." Machine learning technologies such as regularization and steering can be applied to a significant computational problem in seismic exploration - Full Waveform Inversion (FWI), which is a methodology that seeks to find a high-resolution, high-fidelity representation of the subsurface in the ultra-deep Gulf of Mexico."This class of problems is notoriously hard," said Dr. Sverre Brandsberg-Dahl, global chief geophysicist for Imaging and Engineering, at PGS. "It is a multidimensional ill-posed optimization problem that is far from automated and requires lots of skilled resources' intervention - sometimes more art than science in many cases. Our Cray XC40 system was able to learn how to best steer refracted and diving waves for deep model updates and how best to reproduce the sharp salt boundaries in the Gulf of Mexico. Machine learning at scale on our Cray supercomputer showed dramatic improvement in the quality of the inversion process as compared to current state-of-the-art FWI."
