Study gas hydrates by a variety of methods, but the ANS task is focused on determining what is the ultimate resource potential of the known gas hydrate and associated free-gas accumulations on the North Slope. This project will: (1) provide the scientific foundation for drilling of gas hydrates on ANS and Mackenzie Delta; (2) implement regular assessments of the in-place and recoverable energy resource potential of onshore gas hydrates and associated free gas; (3) understand the environmental impacts of hydrate production in permafrost and marine settings; (4) develop conceptual models for source-migration-reservoir hydrate systems; and (5) develop quantitative source-migration-reservoir models of hydrate occurrence. The ANS task is a cooperative effort with BLM-AK, State of Alaska (DOG-DGGS), and DOE, in which specific accumulations of gas hydrate/free gas accumulations are being studied. One specific goal is to conduct a resource assessment of the technically recoverable gas hydrate resources on the North Slope. This will be the first time that any gas hydrate resource assessment will be anything other than in-place numbers.
