Abstract:
A sample of frozen rocks is placed into contact with a frozen solution of an X-ray contrast agent at subzero temperature. Upon the end of saturation of the sample, a computed X-ray microtomography of the sample is conducted at a subzero temperature. The obtained microtomographic image is analyzed and spatial distribution and concentration of ice and/or gas hydrate inclusions, as well as open and closed porosity are determined.
