In this study, geological consideration and thermal characterization of oil shale samples were studied. Geological considerations of oil shale samples were studied using Rock-Eval analysis and it was observed that the kerogen type of all oil shale samples were in the majority of Type-I and II. Thermal characteristics and kinetics analysis of oil shale samples were studied by non isothermal differential scanning calorimeter (DSC) and thermogravimetry (TG/DTG). In air atmosphere, two different mechanisms causing loss of mass were observed known as loss of moisture, and decomposition of kerogen and bitumen. Kinetic parameters of the samples are determined using ASTM-I and II (DSC), Kissinger, and KAS (TG-DTG) kinetic models and the results are discussed.
