In deep sedimentary basins, geothermal processes are significantly affected by heat transport properties. In this study, thermal properties of deep sediment core samples were measured using a thermal constant analyzer with transient plane source method. Results showed that thermal conductivity of the sediment near the seafloor was low and increased with depth. Thermal conductivity of coal was lowest of all samples, while cemented rock exhibited the highest thermal conductivity....
Hydrate bearing sediments, found in permafrost, have great potential as a future energy source. Therefore, the thermal properties need to be determined to design drilling and gas extraction processes. The thermal conductivity was measured through a transient plane source (TPS) method. The thermal conductivity values show weak negative dependence on temperature. The effective thermal conductivity of hydrate-bearing sediment is strongly dependent on the water-saturation of the sand, the hydrates tend ...
