Abstract
The occurrence of gas hydrates in the Mackenzie Delta-Beaufort Sea region raises a number of concerns for resource and hazard assessments and for global change studies in permafrost regions. In preparation for a major gas hydrate research well planned for February 1998, a detailed evaluation of terrestrial gas hydrate occurrences has been undertaken in the Mackenzie Delta-Beaufort Sea region. This evaluation included the review of the gas hydrate geologic setting, sediment associations, pressure and temperature conditions. After an exhaustive review of all the inferred gas hydrate occurrences in the Mackenzie Delta-Beaufort sea region, it was determined that the Mallik L-38 drill site offered the highest probability of encountering thick gas hydrate occurrences. Open hole well logs reveal that the Mallik L-38 well drilled about 111 m of gas-hydrate-bearing strata within the depth interval from 810.1 to 1,102.3 m, which is within the zone of predicted methane hydrate stability and below the base of ice-bearing permafrost.
