Methane Hydrate Formation and Dissocation in a Partially Saturated Sand--Measurements and Observations
We performed a sequence of tests on a partially water-saturated sand sample contained in an x-ray transparent aluminum pressure vessel that is conducive to x-ray computed tomography (CT) observation. These tests were performed to gather data for estimation of thermal properties of the sand/water/gas...
