Lithofacies classification

WebWe present a technique for lithofacies classification of well-log data using an active semi-supervised algorithm. This method considers both the input of domain experts and the distribution characteristics of well-log properties. Web1 jan. 2024 · Lithofacies classification scheme for the HRZ Shale. We used different quantitative values (cut-offs) of clay, quartz, pyrite, and TOC content to classify mudstone lithofacies in the HRZ Shale. Unlike the Wolfcamp and Eagle Ford Shale in Texas, we do not use carbonate as its proportion is insignificant in the HRZ Shale.
