Description
Jintao Kong, Xianyue Xiong, and Rong Ding set methods to split a deep coal seam and classify its facies, in work from 2025. Deep coalbed gas in the Ordos Basin is now produced at scale. Fine study of seams buried past two thousand meters has become urgent.
Their target is the eighth seam in one block on the basin's eastern edge. Well logs feed a tuned regression model that estimates two facies indexes. Clustering then sorts the seam into facies types under a sequence framework. Model errors and fit scores are reported for both indexes. The scheme suits local geology and can guide gas well placement.
