The thermal conductivity of hydrate-layer sediment recovered from a location near Japan was measured at temperatures ranging from 263-283 K, and at a pressure of 0.1 MPa. The thermal conductivity of Toyoura standard sand as a comparison. The thermal conductivity of the methane hydrate-bearing sediment was found to be lower than that of the standard sand at the same temperature. These samples were then measured at conditions similar to those below ...
