Evaluation of common mixing models for calculating bulk thermal conductivity of sedimentary rocks: Correction charts and new conversion equations

► We compare the most common matrix-pore models for thermal conductivity calculation. ► The geometric mean model shows the best fit between measured and calculated values. ► Correction equations improve the goodness of fit; the resulting errors are lower than 10%. ► Conversion equations allow a calculation of water-saturated BTC only from dry measurements.
