Abstract
The work describes a new developed cell, which allows simultaneous acoustic measurements and X-ray tomography of hydrate-bearing samples. The results of the first experiments on the formation of xenon hydrate in a sand sample by the “excess gas” method are presented. The formation of gas hydrate in the sample led to compressional wave velocity increase associated with cementation of granules with hydrate. The obtained tomographic images showed that formed xenon hydrate envelops sand granules. A uniform distribution of hydrate in the pore space in the scan area is also observed.
