The Mackenzie permafrost, located at Northwest Territories, Canada, is one of the most important gas hydrate inventories all over the world and conventional petroleum basins in Canada. Mallik L-38, 2L-38, 3L-38, 4L-38 and 5L-38 wells for gas hydrate or conventional petroleum have been drilled in the Mallik gas hydrate field, the Mackenzie Delta, and a broad of research activities including regional geology, geophysics, geochemistry, microbiology, logging, production testing and modeling, and etc., have been undertaken, which accumulated a vast amount of data and technical research papers. Therefore, the Mallik gas hydrate field has come to be known as more scientists and engineers on gas hydrate investigation and research. A suite of well constrained short-term production tests by depressurization and thermal-stimulation techniques were undertaken and successful on the Mallik 2002 Gas Hydrate Production Research Well Program, which confirms the feasibility of natural gas production from gas hydrate. The Mallik 2002 Program is a milestone in gas hydrate exploitation, which has provided a basis for future long-term production test and production strategies. It is believed that the potential of gas hydrate as an energy source is likely become as an energy commodity in the future.
