2D facies distribution through SOM are created using GR, CNL, AC, and DEN log data. A color index shows each log's contribution. (a) Dispersed maps of utilized logs before calibration. (b) Cluster randomization plot showing the ideal number of clusters. (c) SOM-clustering results after calibration. (d) A dendrogram showing the group of three identified clusters.
