Abstract: Gas hydrates have potential to be used as future energy sources, so it is important to understand their thermal properties. This paper aims to examine the effective thermal conductivity of synthetic porous methane hydrate samples. A Hot Disk Thermal Constants Analyser measured the thermal conductivity of the methane hydrate samples using the single-sided transient plane source (TPS) method. Results showed an inverse relationship between porosity and thermal conductivity. Unfortunately, mechanical pressure can reduce pore size of the samples to increase thermal conductivity, but cannot completely eliminate them.
