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.

In September 2004, the American Association of Petroleum Geologists (AAPG) convened a Hedberg Research Conference in Vancouver, British Columbia, Canada titled "Natural Gas Hydrates: Energy Resource Potential and Associated Geologic Hazards." As a continuation of the Hedberg Research Conference in Vancouver, the conveners of the conference and the editors of this Memoir have worked with more than 150 authors and coauthors to prepare this Memoir on gas hydrates. This publication follows the goals of the Hedberg conference; however, the contents of this Memoir were expanded to include all aspects of gas hydrates in nature. This Memoir contains 39 individual contributions, ranging from long topical summaries to shorter focused research papers. This Memoir has been published in two parts, with digital versions of all the complete research papers included on the enclosed CD. The hardcopy portion of the Memoir includes abstracts and several key figures for each of the contributions along with a complete copy of a gas hydrate technical review. The digital portion of this Memoir has been organized into a series of topical sections consisting of review articles, marine gas hydrate papers, and gas hydrate laboratory and modeling studies. Because of the rapidly emerging worldwide interest in gas hydrates, this comprehensive treatise on the geology of gas hydrates will be valuable to both the gas hydrate research community and exploration/development geologists working in arctic and deep marine environments.
