The course provides basic knowledge of source rocks and oil and gas geochemistry, basics of major analytical methods and methods for the interpretation of laboratory data. The microscopic methods and Rock Eval pyrolysis is introduced. The phenomenon of thermal maturity on the basis of Tmax and Ro, the type of hydrogen existed since the index, and the d13Corg, Corg / Norg and potential of the CH-determination of S1 and S2. The correlation of biomarkers and source rocks using isotope ratios is discussed. The development of thermal and bacterial degradation of the CH-plants are discussed on the basis of composition, API degrees and the gas chromatographic fractions of saturated character. We pay special attention to the oil and gas migration, the unconventional CH accumulation (gas hydrate, oil sands) and geochemistry of inorganic gases. Inorganic hydrocarbon formation theories are discussed for the outer and the inner planets. Certain extremely rich source rocks (Ordovician Gass shale, Silurian Tanezuff shale, Carboniferous Bakken Shale, Jurassic Kimmeridge Clay, Niobrara Shale, Oligocene Tard Clay) are described, including their geochemical characteristics and facies conditions.
