Machine Learning in Geoscience – December SIG Meeting

Applications of Supervised deep learning for Seismic interpretation and inversion

With Dr York Zheng at BP


The adoption of modern machine learning techniques by the oil and gas industry has been rapid, but obtaining robust results from their applications to real seismic data is still challenging.  In this talk, two different case studies are presented to demonstrate supervised deep learning as an alternative to conventional techniques for seismic interpretation and inversion.  The first example is a classification problem, in which a convolutional neural network (CNN) is trained to pick faults automatically in 3D seismic volumes.  The second example is on elastic model building, re-casting pre-stack seismic inversion as a machine learning regression problem.  In both cases, I show that CNN models can be trained on synthetic data and subsequently used to make efficient predictions on field data, whilst also highlighting some of the challenges of applying supervised learning techniques to seismic data.
