Résumé(Sommaire disponible en anglais seulement)
The hydrocarbon reservoir potential in Paleozoic strata in the Hudson Bay Basin in northern Canada is evaluated from petrophysical log analyses of five offshore wells (Walrus A-71, South Narwhal O-58, Polar Bear C-11, Beluga O-23 and Netsiq N-01).
The petrophysical analyses of wireline logs, integrated with core and thin section data, provide information on lithology, porosity, permeability and water saturation. The analyses indicate that many limestone, dolomite, sandstone, and conglomerate intervals within the Paleozoic succession have sufficient porosity and permeability to form good quality hydrocarbon reservoirs. The best reservoir characteristics occur in carbonates in the Devonian Williams Island and Kwataboahegan formations and Silurian Severn River Formation. Formation pressure and permeability data indicate effective seals are present in the basin. Water saturation calculations from log data
indicate possible hydrocarbon zones occur in all wells and at many stratigraphic Levels. Well history records indicate hydrocarbon shows were encountered in some reservoir intervals. The observations of good quality reservoirs, effective seals, possible hydrocarbon-saturated reservoir intervals and hydrocarbon shows, highlight the potential for hydrocarbon resources in the Hudson Bay Basin.
