AbstractThe Ogilvie Platform Composite Tectono-Sedimentary Element (CTSE) occupies an area of about 68 000 km2 in the northern part of the Yukon Territory of Canada, and includes all Paleozoic- and Triassic-aged strata between a base of Cambrian unconformity and a base of Jurassic and Cretaceous unconformity. This cratonic platform is composed of two lithologically distinct sedimentary successions: a lower suite of peritidal to shallow-subtidal, carbonate-dominated, Cambrian-Middle Devonian-aged units; and an upper succession of siliciclastic-dominated alluvial fan, shelf delta, nearshore, slope and basinal strata of Middle Devonian-Late Permian and Triassic age. The lower succession is composed of a synrift tectono-sedimentary element (TSE) and an overlying passive continental-margin TSE. The upper succession is composed of an Ellesmerian orogenic foreland TSE and a syn-epeirogenic TSE. The total discovered oil reserve within the Ogilvie Platform is estimated to be 1.757 × 1000000 m3 (11.05 MMbbl) and the total discovered gas reserve is estimated to be 2.376 × 1000000000 m3 (83.7 Bcf) in four oil and gas pools. A variety of stratigraphic and structural trap types have been assessed to contain additional conventional hydrocarbon reserves, with a total mean potential of 33.4 × 1000000 m3 (210.1 MMbbl) of oil and 33.4 × 1000000000 m3 (2.63 Tcf) of gas. The organic-rich shale and siltstone-dominated petroleum source-rock units, such as within the Road River Group, the Canol and Ford Lake formations, and organic-rich strata within the Hart River and Blackie formations, are also prospective for large reserves of unconventional oil and gas, and have yet to be formally assessed.
Summary(Plain Language Summary, not published)
Ogilvie Platform occupies an area of about 68,000 square kilometers in northern Yukon Territory, and includes all Paleozoic-aged strata between the base of Cambrian unconformity and overlying Mesozoic strata. It is comprised of two distinct sedimentary successions; a lower, rifted, passive continental margin suite of carbonate-dominated, Cambrian- to Middle Devonian-aged units, and an upper, orogenic foreland basin suite of siliciclastic-dominated Middle Devonian to Late Permian-aged strata. The total discovered oil reserve is estimated to be 1.757 x 106 m3 (11.05 million barrels (MMBO)) of crude oil and the total discovered gas reserve is estimated to be 2.376 x 109 m3 (83.7 Bcf) of natural gas.
