Fifty-one resource assessments for Arctic Canada, completed between 1973 and 2022, were identified and evaluated. Of these, 24 are considered to be relevant in that they contain quantitative resource assessments, and an additional eight are prospectivity maps.
The assessment areas considered in these reports are the Beaufort-Mackenzie Delta region, the deep water Canada Basin that occupies the floor of the Arctic Ocean; the Arctic Margin from Banks Island to northern Ellesmere Island; the Sverdrup sedimentary basin underlying the northern Canadian Arctic Islands, the Lincoln and Makarov basins that lie north of Ellesmere Island and Greenland; the Baffin Margin that lies between Baffin-Devon-Ellesmere islands and Greenland; the Franklinian Margin that underlies the southern Arctic Islands, and the Foxe Basin that lies southwest of Baffin Island.
The assessed values have been standardized to recoverable barrels of oil equivalent (BOE) for those assessments reporting both oil and gas. Gas is converted to oil equivalent using the industry standard ratio of 6000:1. The range of mean estimates of recoverable BOE for each assessment area is shown by green bars in Figure 1; the mean estimate of recoverable BOE for an individual assessment is represented by a black circle. The four Baffin Margin assessments split geological provinces differently and cover spatially distinct geographic areas making it difficult to directly compare results. Deep water assessment areas in Baffin Bay have been apportioned 50% to Canada for this summary. The assessed resource for Lincoln Sea by Sørensen et al. (2011) includes Canadian and Greenland waters.
Evolving geological knowledge and improvements to methodology and computing power mean that the values reported for the same assessment area will change over time. All the historical assessments reviewed in this report have at least some limitations that affect their accuracy.
Summary(Plain Language Summary, not published)
This report summarizes historical hydrocarbon resource assessments from northern Canada that were published between 1973 and 2022. The area with highest assessed hydrocarbon resources is the Beaufort-Mackenzie region of the western Arctic/Northwest Territories.
