Theory-guided data science-based reservoir prediction of a North Sea oil field

The Leading Edge | Jon Downton, Olivia Collet, Dan Hampson, Tanya Colwell © 2020 SEG

Data science-based methods, such as supervised neural networks, provide powerful techniques to predict reservoir properties from seismic and well data without the aid of a theoretical model. In these supervised learning approaches, the seismic to rock property relationship is learned from the data. One ...
