Artificial neural network modeling and cluster analysis for organic facies and burial history estimation using well log data: A case study of the South Pars Gas Field, Persian Gulf, Iran

► Rock-Eval pyrolysis on drill cutting samples. ► Formulating the TOC values to well logs using ANN and Δlog R methods. ► Clustering the generated TOC data into specified zones by Cluster Analysis. ► Drawing the burial/thermal history diagrams for each zone. ► Correlating the estimated data with the achieved real data.
