Hydrates of natural gas exist in nature in the Arctic regions and underneath the sea floor. Worldwide reservoir estimates range as high as 10/sup 7/ trillion ft/sup 3/. Very little information is available about the physical properties of these deposits, thus making difficult their detection by remote geophysical surveys. Reviewed are experimental sonic and resistivity measurements on hydrates, hydrate-bearing sediment, and permafrost. Conclusions indicate that hydrate layers are characterized by anomalously high sonic velocities and resistivities, both of which are functions of the amount of liquid water associated with the hydrates in the rock matrix. An analogy between hydrate-bearing sediments and permafrost is used to propose simple quantitative relationships between liquid water content and the electrical resistivities and sonic velocities of the deposits. Electrical and sonic well-logging data are used to substantiate the basic conclusions of this review. 18 references, 6 figures, 2 tables.
