    Abstract

    Continuous vertical variations of thermal conductivity were registered using optical scanning technique at 847 full-size core samples of the oil field located in West-Siberia. Target interval is highly heterogeneous and anisotropic oil-source rock - the Bazhenov formation. Thermal core logging and well logging data were integrated for shale reservoirs thermal conductivity prediction. Correlation analysis between neutron porosity and thermal conductivity was performed. The vertical resolution of the corresponding logging tool was considered. The obtained regression equation was used for thermal conductivity prediction. Mean absolute percentage error is 8 %. For shale oil thermal conductivity prediction volumetric mineralogical model from standard well logs was constructed. Using different mixing rules including the Liechtenecker equation vertical variations of thermal conductivity were predicted. Mean absolute percentage error is 6.6 %.
