Résumé(disponible en anglais seulement)
The hydrocarbon resource potential of the Hudson Platform is being studied as part of the Geological Survey of Canada (GSC) Geo-Mapping for Energy and Minerals (GEM) program. The first phase of the GEM program started in 2008 and concludes in 2013. This presentation will highlight results of the Hudson Platform GEM project to date, focussing especially on those from northern Ontario. Project partners include geological surveys of Ontario, Manitoba and Nunavut, as well as numerous university researchers and students from Canada and abroad.
Significant GEM project results include: biostratigraphically guided revisions to the Paleozoic stratigraphy of the platform; identification of a major unconformity at the Silurian-Devonian boundary; identification of Upper Ordovician, fault-related hydrothermal dolomite reservoirs; identification of by-passed potential hydrocarbon reservoir intervals from re-evaluation of electric logs in offshore wells; Rock Eval 6® and organic matter reflectance data indicating Ordovician source rocks in the Hudson Bay Basin are thermally mature; discovery of circular sea-floor depressions in Hudson Bay, similar to fluid or gas-escape pockmarks; and the discovery with Radarsat® technology of potential oil slicks on the surface of Hudson Bay.
Work for this project in northern Ontario included logging and sampling of available archival cores and mineral exploration cores in the field, reconnaissance scale field mapping and undertaking large aeromagnetic surveys over the Hudson Bay Lowlands. Results of this work include: discovery of mid-Tertiary sediments; confirmation and expansion of the occurrence Upper Ordovician source rocks in northern Ontario; organic matter reflectance data suggesting that this source rock is thermally mature; and revisions to existing maps. On-going work includes combining lithostratigraphic core logs with new biostratigraphic and chemostratigraphic analyses to develop a modern stratigraphic framework for the Hudson Platform in Ontario.
