Abstract

We have presented a summary of measurements on the physical properties of sediments relevant to methane hydrate recovery. The data includes not only geotechnical determinations, but also the CMT data that gives porosity values and pathways through the sediment material. The results show that CMT techniques can be used to study sediment properties on a micrometer-size scale. Since the technique is non-destructive, changes in the sediment microstructures as a function of pressure and temperature can be measured. It is also feasible to look at formation of methane hydrates in the sediment structure as has already been demonstrated [7–9]. A longer term challenge is to start from the microscale data and calculate the macroscopic quantities shown in Table 2. We also note that the CMT measurements help in identification of different minerals found in the sediments. This feature of CMT was not exploited in this survey.
