Learning Outcomes
Introduction to Organic Petrography/Petrology, the coal-petrography microscope, and identification of organic material and its characteristics.
Course Content (Syllabus)
The organic matter under the microscope: maceral (in coal) and bitumen (in source rock). The maceral groups of huminite/vitrinite, liptinite, inertinite. Kerogen, migra- and pyrobitumen. Huminite/vitrinite and bitumen reflectance as measure of rank and maturation of organic matter in coal and source rock, respectively. Biomarkers. Analytical methods: Gas Chromatography, full-scan Gas Chromatography-Mass Spectrometry. The chemistry of biomarkers. Application of biomarkers in petroleum exploration. Application of biomarkers in basin analysis. The biomarkers as indicators of depositional conditions and accumulation of organic matter in source rocks. Thermal maturity assessment based on biomarker analysis. The biodegradation process. MP1 index and its relation to VRo. The palaeo-pasturization effect. Petroleum age and biomarkers. Examples of biomarker analysis from Greek and international hydrocarbon fields.
