Summary:
The subject of this thesis is the source rocks in the region of Western Greece and Albania. The aim of the study is to synthesize, through literature and data from wells, the nature and characteristics of the different possible source rocks. Also the mapping of the paleo-environment and describe their evolution through location and time.
In order to meet the objectives of this study, an evaluation of the potential of the possible source rocks has to be done first as well as classification in categories according to their potential. For the evaluation of the possible source rocks we have to use the available geochemical analysis of the samples and define their characteristics and parameters as TOC (total organic carbon), S2 (mg TOC / gr rock), HI (Hydrogen Index), OI (Oxygen Index) and stage of maturation. For the mapping of the paleo-environment, the depositional environments of the source rocks were first identified and then presented on a paleo-geographic map.
The best source rocks, as expected, were found in the Ionian Zone in the Triassic, Lower and Upper Jurassic, and Middle Cretaceous. However, very good source rocks were found in the Kruja zone in Albania, in the Upper Cretaceous. The depositional environment of the best source rocks is deep marine, while good source rocks are found in supratidal environments. Therefore, it is difficult to make a clear determination of the relationship between good source rock and depositional environment.
