Project Objective
Oil and gas potential of the Mackenzie Corridor and surrounding areas is the focus of a Northern Energy project under the Secure Canadian Energy Supply Program of the Earth Sciences Sector (ESS) - (Geological Survey of Canada (GSC)) of the Department of Natural Resources Canada (NRCan). The main objective of this multidisciplinary project is to assess the hydrocarbon resource potential of the Mackenzie Valley using quantitative and qualitative geoscience data. Although significant hydrocarbon discoveries have been made along the Mackenzie Valley, such as the Norman Wells oil field in Mackenzie Plain and large gas fields in Liard Plateau, the potential for the discovery of economic accumulations of petroleum in several exploration regions is still poorly understood. Insufficient
stratigraphic, structural, and geochemical data preclude a comprehensive assessment of some areas. The study will encompass much of the Interior Plains, Mackenzie Mountains, and eastern portion of the Northern Yukon exploration regions. It is a collaboration between the Geological Survey of Canada, the Northwest Territories Geoscience Office, the Yukon Geological Survey, industry, universities, and northern communities.

Work in progress
Several exploration plays have been identified and will be the focus of future work, such as the Plateau Thrust play in the central part of the Mackenzie Mountains, fault traps within Cambrian and Devonian sandstones and carbonates, and stratigraphic and structural “foothills” plays in Mackenzie Arc. Fieldwork in 2006-2007 will be conducted to 1) examine stratigraphic sections and evaluate potential source and reservoir facies, 2) collect samples for organic geochemistry analysis, 3) study the role of structural features as hydrocarbon conduits, and 4) assess the viability of probable structural and stratigraphic traps.
Fieldwork 2006
Fieldwork was conducted along the northern front of Mackenzie Mountains. Key objectives are to reevaluate the geometry, kinematics, and timing of key Phanerozoic regional structures and to reexamine the effect of Proterozoic tectonism on the orientation of these structures. Observations will be integrated with seismic data to reassess potential petroleum traps across the region. Work was conducted in southern Peel Plateau and Plain and northern Mackenzie and Franklin mountains, through the southern half of Upper Ramparts (NTS 106 G) and Sans Sault Rapids (NTS 106 H) map areas with reconnaissance work done in the southeast corner of Snake River (NTS 106 F) map area. Detailed structural mapping was carried out along major structures, such as Tabasco, Deadend, and Southbound faults as well as across Imperial anticline.
