Popis: Upper Jurassic studies, based on well correlation, stratigraphy, and well-logging analysis, allow us to define six sedimentary units of M’Rabtine formation in the Gulf of Gabes. Unconformities characterized by the absence of the evaporitic member (MEVP), unit of M’Rabtine formation (Kimmeridgian–Tithonian), in the most western part and the gap of the M’Rabtine formation in the most eastern part of the study area give us an idea of the paleogeography and the variation of deposit environment. Petrophysical evaluation and lithological determination from well-logging data show that sedimentary unconformities and facies lateral variation are related to salt tectonic and/or probably eustatic events. Reservoir parameters show grained sandstone units defined as potential reservoirs and producing hydrocarbon in P6 and P8. M3 and M5 units in P6 are a good oil reservoir with a porosity average between 17.5 and 25 %. In P8, M3, M4, and M5 correspond to the aim reservoir with a porosity average between 24 and 29 %.
