| Résumé | (Sommaire disponible en anglais seulement)
Research on hydrocarbon systems for the Hudson Bay (GEM 2 program 2014-2020) has initially focussed on detailed source rocks kinetic and potential
hydrocarbon reservoir appraisal. Upper Ordovician reefs are sizeable mound structures in outcrop and on vintage seismic profiles. In outcrop, the reefs are porous (15-25%) with bitumen coating some pore space. The reefs are on top of high TOC and HI
source rocks. Conventional and cathodoluminescence petrography has identified different cement phases (early marine to late cements) which were characterized with oxygen (delta-18O) and carbon (delta-13C) stable isotopes and fluid inclusion
microthermometry; clumped isotopes signature (delta47) on late cements will be acquired for more temperature constraints on late cements.The Upper Ordovician reefs had significant open porosity at the time the slightly older source rocks entered the
oil window. |
