Abstract
Due to the importance of the petroleum discoveries in the Pelegian domain and the poor knowledge of the hydrocarbon systems, a geochemical evaluation based on samples collected from different wells and layers—Aptian (Serdj formation), Albian (Lower Fahdene formation) and Yprisian (Bou Dabbous formation) drilled in the Pelagian province, offshore north-eastern Tunisia—should be done to better understand the petroleum system and identify source rock types. The geochemical study aimed to characterize source rock potential and to determine the origin of oil shows recorded in the Serdj Formation through the correlation of extracted oils with the different oils and source rocks present in the neighbouring provinces. This study is based on pyrolysis analysis using the RockEval 6 and on oil characterization using the gas chromatography/mass spectrometry. The present study has shown that the two extracted oils—FI-1 and SE-1—were generated from the Fahdene source rock (Gulf of Hammamet), and that there is no relationship between those oils and the IS oil (Bouddabous source rock, Gulf of Gabes) based on their biomarker distributions (Oil–Oil and Oil-Source Rock Correlations).
