Web31 mrt. 2024 · Abstract. We propose a methodology for the recovery of lithologies from geological and geophysical modelling results and apply it to field data. Our technique relies on classification using self-organizing maps (SOMs) paired with geoscientific consistency checks and uncertainty analysis. In the procedure we develop, the SOM is trained using … Webtransformation. The results of lithological interpretation of well logging data were classified into two classes - reservoir and non-reservoir. Reservoir was encoded as 1, while non-reservoir was encoded as 0. The classification results of well logging data were approximated onto the grid using the dominant frequency of class occurrence in
