THERMAL PROPERTIES OF METHANE HYDRATE BY EXPERIMENT AND MODELING AND IMPACTS UPON TECHNOLOGY

Thermal properties of pure methane hydrate, under conditions similar to naturally occurring
hydrate-bearing sediments being considered for potential production, have been determined both
by a new experimental technique and by advanced molecular dynamics simulation (MDS). A
novel single-sided, Transient Plane Source (TPS) technique has been developed and used to
measure thermal conductivity and thermal diffusivity values of low-porosity methane hydrate
formed in the laboratory. The experimental thermal conductivity data are closely matched by
results from an equilibrium MDS method using in-plane polarization of the water molecules.
MDS was also performed using a non-equilibrium model with a fully polarizable force field for
water. The calculated thermal conductivity values from this latter approach were similar to the
experimental data. The impact of thermal conductivity on gas production from a hydrate-bearing
reservoir was also evaluated using the Tough+/Hydrate reservoir simulator (Revised version of ICGH paper 5646).
