In 1996 the Geological Survey of Canada (GSC), together with the Japan National Oil Corporation (JNOC) and the Japan Petroleum Exploration Company Ltd. (JAPEX) began planning and preparations for the 1998 drilling of the JAPEX/JNOC/GSC Mallik 2L-38 gas-hydrate research well at the Mallik site in Canada's Mackenzie delta, Northwest Territories. In the course of that program, and the subsequent Mallik 2002 gas hydrate production research well program, significant progress has been realized with respect to laboratory research into the properties and behavior of gas hydrate in both artificial and natural porous media. This included the establishment of a basic capability to successfully grow gas hydrate within the pore volume of natural sediments and/or synthetic quartz analogs, development of a dielectric technique for direct quantification of gas-hydrate amounts in laboratory test specimens, determination of the thermal conductivity of gas-hydrate-bearing sediments, and documentation of pressure-temperature-salinity influences on gas-hydrate stability in Mallik reservoir sediments. This work has contributed directly to the fundamental understanding of gas-hydrate occurrences in nature, to the specification of appropriate values for critical parameters used in gas-hydrate production models, and to the design and evaluation of practical production scenarios to be employed in an extended production test of a natural-gas-hydrate deposit anticipated in the near future.
