sand-rich intervals in the Mackenzie Delta region mainly occur as pore-filling material in the sand reservoirs and can also infrequently be observed as coatings around individual sand grains. The gas trapped inside the clathrates is predominantly thermogenic methane that generated due to a thermal alteration of organic material. Given the chemical and carbon-isotope compositions of the organic matter, the organic material is predominantly composed of a variety of higher land plants with a terrestrial origin. In the winters of 2007 and 2008, a smaller participant group, including JNOC and the Geological Survey of Canada, conducted a new Mallik program with the primary objective to install physical installations for production testing and re-injection of produced water, to deploy and evaluate new monitoring systems, and to undertake a short-term pressure drawdown test to gain new and groundbreaking insights prior to undertaking long-term production tests in 2008. Ongoing analysis of the data collected throughout the program will lead to a greater and better understanding of gas hydrate properties and its formation, production response, and the effectiveness of conventional production technologies. Scientific and engineering results were made publicly available to scientists, stakeholders and engineers through the Bulletin of the Geological Survey of Canada (Bulletin 544 and 585). The importance of Mallik as an active study site Mallik, as an ongoing gas hydrate research site, is the first fully integrated field study and modern production test well of natural gas hydrates in Canada. The wells were successfully drilled to test a major natural gas hydrate accumulation in the Mackenzie Delta of the northwestern Canadian Arctic. It gave scientists the opportunity to monitor the physical response of gas hydrate deposits and investigate permafrost gas hydrates in one of its most prominent occurrences. From a technical perspective, the results from the scientific R&D Program in the Mackenzie Delta basin confirmed pre-drill predictions that gas hydrates were present in high-saturation, sand-rich reservoirs. Resultantly, scientists were able to successfully recover wireline cores through the different gas hydrate intervals. Also, experts could carry out cross-hole tomography experiments not only before, but also during and after the actual production tests. During the project, a suite of several different open-hole logs could be obtained by using advanced and new gas hydrate logging tools, giving first insights into the reservoir thickness and general natural gas hydrate saturations. Unfortunately, due to a lack of pipeline or gathering system, there is currently only one field
