Application and Comparison of Machine Learning Methods for Mud Shale Petrographic Identification

Abstract: Machine learning is the main technical means for lithofacies logging identification. As the main target of shale oil spatial distribution prediction, mud shale petrography is subjected to the constraints of stratigraphic inhomogeneity and logging information redundancy. Therefore, choosing the most applicable machine learning method for different geological characteristics and data situations is one of the key aspects of high-precision lithofacies identification. However, only a few studies have been conducted… Show more

“…K-Nearest Neighbor-KNN is an ML algorithm for classification, supervised, non-parametric, discriminating and deterministic pattern recognition method. The algorithm computes the similarity and finds the k the closest training examples in the dataset using the distance function; for the K number of the nearest neighbors, the distance between the query examples and all the training cases is computed using Euclidean distance [27][28][29][30].…”
