Abstract: The thermal properties of synthetic gas hydrate-bearing sediment samples were determined by the transient plane source method. The samples were made up of sand, water, gas, and methane hydrates, and these samples were supercooled to minimize the effects of the heat of fusion of methane hydrate on the thermal conductivity measurements. The thermal conductivity was found to increase with increasing methane hydrate saturation for saturations from 0-0.3. Thermophysical models were examined to determine if they were able to reproduce the experimental data, and thus predict the thermal properties of a four-component sample. It was found that the geometric mean model was best able to reproduce the results; however, this model underestimated the thermal conductivity.
