The study of the petrographic structure medium- and high-rank coals is important from both a cognitive utilitarian point view. constituents their individual characteristics features are responsible for properties coal way it behaves in various technological processes. This paper considers application convolutional neural networks images segmentation. U-Net-based model segmentation was proposed....

microfacies and depositional environments interpretation of asmari and jahrum were studied in boreholes 2, 10 and 11 in gol- khari oil field. based on petrographic criteria, fauna assemblages, biofacies and sedimentary textures, 21 carbonate microfacies and 3 non- carbonate petrofacies were recognized. these microfacies were deposited in distinct depositional environments including tidal flat, ...
