Abstract

Organic geochemistry is scientific discipline used in the process of exploration and production of hydrocarbons. Geochemical results provide determination of source rocks, evaluation of their productivity, efficiency of expulsion, and migration phenomena. At the same time this research provides also genetic characterization of hydrocarbons in reservoirs, their comparison and detection of their alteration. Organic geochemistry is applied to development and production engineering while geochemical results usually complement geological and geophysical research. Geochemical research methods in this paper are demonstrated through the example of source rocks examination from Žutica-1 zapad well. This example describes the concept of organic geochemistry, its methods and how they fit into the hydrocarbons exploration process. After testing of source rocks, comparison of bitumen extracted from rock samples and oil from the Žutica oil field was conducted. The conclusion of this paper explains the differences in molecular content between the bitumen and oil and also offers guidelines for further geological and geophysical research, where these results should be incorporated.
