Abstract

Experimental results on hydrate and ice formation conditions in the pores of sandy sediments during temperature cycles are presented. To better understand how hydrate accumulates in sandy sediments, we measured the accumulation of CH4 and CO2 hydrate and ice in sandy sediments under various conditions. With the pressure above that needed for hydrate formation, cycling the temperature below and above the freezing point of water increased the amount of hydrate in the sediments. The self-preservation effect allowed us to determine the structure and some physical properties of these sediments that contained ice and hydrate.
