Thermal Conductivity of Sedimentary Rocks and Appropriate Corrections for In-situ Conditions

We attempt to remedy the existing deficiency of thermal conductivity data of sedimentary rocks by making a series of measurements in laboratory on several bottom core samples, collected from petroleum explorative wells and representative of the main sedimentary rocks recognized in the western Po Basin, Northern Italy. The in-situ bulk thermal conductivity is then estimated using calibrated formulas taking into account the mineralogical composition, the porosity and the effect of temperature.
