    Abstract

    The development of a thermal core logging technique as a field-scale geophysical technique presented new possibilities for multiphysical testing of shales, e.g. preparation of representative databases of the thermal properties for basin modeling and hydrodynamic modeling for thermal methods of EOR, and practical application of correlations between shale thermal conductivity and total organic carbon. The technique of determination of oil shale total organic carbon from the thermal core logging data was developed that provides detailed continuous high-resolution profiling total organic carbon of oil shales along wells. The technique was studied and tested on more than 11 500 oil shale samples from Bazhenov and Domanic Formations when more than 1250 shale samples were also tested for total organic carbon content with Rock-Eval pyrolysis. The data on shale total organic carbon obtained from the measurements with pyrolysis allow to calibrate and control the results of total organic carbon determinations from the thermal core logging. Continuous profiling total organic carbon from continuous thermal core logging provides reasonable selection of shale samples for future investigations and are basis for basin modeling and calculation of reserves.
