| Abstract | The 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. |
