f Estimating thermal conductivity from geophysical well logs: Selected boreholes in Danish sedimentary basins

Estimating temperatures in sedimentary basins and geothermal reservoirs requires knowledge of heat flow, thermal conductivity, heat production, and the surface temperature history. Contrary to heat flow, thermal conductivity typically shows large local variability, both on vertical and horizontal scale, resulting in large variations in temperature gradients. Accurate estimates of thermal conductivity are thus of paramount importance.
