AbstractThe intermontane Eagle Plain Basin lies within the mountainous and deformed Northern Yukon Fold Complex geological province of the northern mainland of Canada. This Paleozoic-Mesozoic basin forms a petroleum province that is less deformed and less structurally elevated compared to surrounding mountain belts. The Eagle Plain Basin contains the Eagle Fold Belt which consists of bundles of en-échelon folds that have wavelengths of several to tens of kilometres. The folds developed during the Laramide Orogeny and form well-defined structural closures suitable for entrapment of hydrocarbons in the subsurface.
Several assessment studies of petroleum potential have been completed for the Eagle Plain Basin. Recent work associated with the Geomapping for Energy and Minerals Program interpreted petroleum exploration play concepts not previously defined. Evaluations of new petroleum data indicated the need to re-assess the conventional oil and gas potential of the basin. In this study, a total of 21 conventional petroleum exploration plays are defined. Also, the potential for unconventional tight oil and gas, and shale oil and gas accumulations (not previously assessed) are included in the report. Given the fact that some conventional plays and all of the unconventional plays were not quantitatively analyzed because of insufficient data, the total petroleum resource indicated in this study is likely a conservative estimate, as there is evidence for hydrocarbon charge in these non-assessed plays.
The probabilistic assessment of total oil and gas potential (discovered and undiscovered) for all Phanerozoic sedimentary strata in Eagle Plain and its environs is 52.2*106 m3 (329 MMBO) of oil and 96.7*109 m3 (3.4 Tcf) of gas (in-place mean volumes). Although there are sizeable discovered reserves (3.2*106 m3 (20 MMBO) of oil and 4.6*109 m3 (165 Bcf) of gas), undiscovered resource potential is significant, as exemplified by the prediction of 2 remaining undiscovered oil pools with mean in-place volumes greater than 4.0*106 m3 (25.2 MMBO) and 4 gas pool sizes greater than 2.0*109 m3 (71 Bcf).
Summary(Plain Language Summary, not published)
New geological information derived from the Geomapping for Energy and Minerals Program prescribed a need to re-evaluate the petroleum potential of the Eagle Plain sedimentary basin in northern Yukon. This Open File document provides a comprehensive discussion and statistical analysis of the conventional petroleum potential of the basin.
