Understanding geological heterogeneities that result from geological structures are important research areas for many applications such as CO2 storage underground; geothermal energy management; and geological hazard studies. The application of Deep Neural Networks (DNN) in geoscience is mainly in the seismic interpretation related tasks (Fig. 1, a light U-Net from Bonke, 2022). The size of data used for training in the interpretation of subsurface data (e.g. seismic data) is not as large as the other disciplines, where DNN algorithms were originally developed. In addition, the architecture of most of networks, and hyperparameters are designed for prediction or classification of problems with less complexity and a lot more training data compared to subsurface data. The objective of the research is to modify the architecture of Deep Neural Networks to fit classification of geological structures. This would be in collaboration between geosciences and mathematics departments at UiO.
