Electrofacies and Depositional Environments of Sajau Coal Formation in Berau Basin, Northeastern Kalimantan, Indonesia

Diana Putri Hamdiana, Abdurrokhim, Yoga Andriana Sendjaja

Abstract: This study analyses depositional environments of the Early Pliocene Sajau Coal Formation, northeastern Berau Basin, based on cores and well log data. On basis of log pattern and lithology composition the lithofacies in this area can be grouped into 4 lithofacies i.e sandstone, coal, clay and shale. This lithofacies suggests that this Sajau Formation have been deposited in Fluvial, Upper Delta Plain and Lower Delta Plain setting and represents transgressive succession. This transgressive succession is controlled by tectonic subsidence

Keywords: Coal, depositional environment, lithofacies, Sajau Formation, Berau Basin
