The Canada Basin is a 1,000,000 km2 deep-water basin adjacent to the continental margins of Arctic Alaska and northwest Canada. Perennial ice cover in the Arctic Ocean has
historically prevented detailed geologic study of the basin. Recent seismic surveys (2007 to 2011) provide substantial new information on crustal architecture and sediment fill of the basin. These geophysical data provide a new framework for a
regional study of petroleum resource potential. This report presents the first quantitative assessment of oil and gas potential in the Canada Basin
Five conventional petroleum plays were defined in Canada Basin, four of which had sufficient data
to perform probabilistic volumetric resource calculations. All of the assessed plays have oil and natural gas potential. To validate the volumetric play assessment results, an independent basin-scale global analogue resource appraisal was also
completed. This technique derived petroleum resource estimates for Canada Basin from geologically comparable petroleum-producing global basins.
The volumetric probabilistic assessment of total oil and gas potential for Cenozoic strata in the
deep-water Canada Basin predicts 2601 million m3 (16361 million barrels) of oil and 1105.7 billion m3 (39.0 Tcf) of gas (in-place mean volumes). Recoverable basin potential is estimated to be 910 million m3 (5726 million barrels) oil and 718.7
billion m3 (25.4 Tcf) gas. The largest individual oil and gas fields in the basin have estimated mean recoverable volumes of 63 million m3 (399 million barrels) oil and 43 billion m3 (1.5 Tcf) gas. The independent assessment based on the global
analogue methodology indicates total recoverable volumes of 6.4 billion barrels oil and 27.5 Tcf gas, similar to the volumetric estimates.
Unconventional petroleum accumulations, including shale oil, shale gas, and natural gas hydrates are likely
to occur in Canada Basin, but quantitative assessments of these resources were not possible due to insufficient data.
This assessment study provides important new insights into the petroleum resource endowment of the deep-water Arctic Canada
Basin, a region with currently unresolved international jurisdiction issues.
|Summary||(Plain Language Summary, not published)|
Perennial ice cover in the Arctic Ocean has historically prevented detailed geologic study of the basin. Recent seismic surveys (2007 to 2011) provide
substantial new information on crustal architecture and sediment fill of the basin. This study presents the first comprehensive quantitative assessment of oil and gas potential in the Canada Basin. Five conventional petroleum exploration plays were
defined in Canada Basin, four of which had sufficient information to perform volumetric resource calculations. All of the assessed plays have oil and natural gas potential. In addition, unconventional petroleum accumulations such as natural gas
hydrates are expected in the basin.
