Combined Pyrolysis Methods to Mitigate Sorbed Hydrocarbon Effect on Kinetic Response: A Case Study from Albian Units, Sw Iran

International Meeting on Organic Geochemistry (IMOG), pp. 1–2

Abstract

Summary Organic matter-rich, oil-prone, marine Albian units are the main source rock for the Upper Cretaceous-Tertiary reservoirs in southwest Iran and adjacent offshore areas. Its paleo-depositional environment encompasses a variety of coastal plain to inner and outer shelf settings resulting in temporal and spatial variations in source rock quality and quantity and presumably the kinetic response. This study attempts to add new bulk and molecular geochemical characteristics for these Albian units as well as its kinetic response considering the variations in the paleo-depositional environment employing different techniques, PY-GC-MS, GC-FID, GC-MS, and GC-IRMS. The results indicate prominent temporal and spatial organofacies variations in the region which is in line with petrographic investigations and bulk and molecular properties of the samples. It also indicates the importance of geological process modeling and preparation of organofacies extension maps for implementing the Albian kinetic response in the regional basin modeling study.
