Abstract: Methane Hydrates have the potential to be a significant energy source as they contain large amounts of methane gas. Large reserves exist in deep sea sediments, and work is being performed to better understand physical characteristics of these sediments. In this article, artificial methane hydrate sediments were created by mixing synthesized hydrate powder with "Toyoura Standard Sand". The thermal conductivity of these samples were then investigated at both atmospheric and high pressure conditions to mimic the pressure they face when buried in the sea floor. Three models were applied to predict values as well. Conclusions included recognition that detailed information on the structure of naturally occurring sediment is vital.
