Outline of Final Research Achievements

For the improvement of reliability of methane hydrate (MH) simulators, the availability of accurate thermal properties of deposits is of crucial importance. Though these properties are measured through core analysis in oil fields, core analysis for MH is technically challenging since the MH could be dissociated during the transportation from the bottomhole to surface. In this research, therefore, laboratory tests, interpretation of field tests and numerical simulations were carried out to establish the in-situ evaluation procedures of thermal conductivity of MH deposits.
