The present study deals with the faciologic and chemostratigraphic characterization of the oil shale interval of the TremembéFormation(Oligocene, TaubatéBasin), and the economic evaluation of these deposits in the Pindamonhangaba and Moreira Cesar,SP regions. From the systematic sampling of the MOR-SP borehole, we determined TOC, S and IR contents, as well as data from Rock-Eval pyrolysis. Based on these data, six chemostratigraphic units (designated from I up to VI in the base) were defined in the interval of about 40 meters in thickness. Data previously studied of TMB-SP and PND-SP wells were used for correlation of these units. Based on data from Rock-Eval pyrolysis, it was possible to quantify the volume of oil potentially recoverable through industrial exploitation of bituminous shale. In the most promising interval (units V and VI), comprising a section of about 17 meters thick, the oil yield is about 25.7 million barrels perkm2 in the area of MOR-SP well. The data point is an important deposit of non-conventional bituminous shale (oilshale), which sees an economic use, if implemented, will require additional new technological solutions, the implementation of actions to minimize the social and environmental impacts of a possible extractive operation of this resource.
