... on conventional well-logging data of 13 exploration wells. In the analysis, methods of change-point analysis for segmentation and fuzzy c-means clustering for log facies classification were integrated. As a result, five log facies (LF), named LF 1 to 5, were identified. These log facies were interpreted...
