AbstractMineralogical surveys are an important part of shale reservoir studies. New results, based on X-ray diffraction analyses (XRD), are reported here for 101 core samples from three wells, mostly from organic-rich mudrocks of the Horn River Group (HRG) in Mackenzie Plain area. The combined NTGS-GSC XRD database has sufficient resolution for robust mineralogical characterization of stratigraphic units. The Canol Formation has the highest quartz (82% median) and the lowest clay content (7% median). Clays in the HRG are dominated by illite. The Hare Indian and lower Canol formations are variably calcareous and dolomitic; the upper Canol is dolomitic but non-calcareous; basal Imperial shales are sideritic-dolomitic and non-calcareous. More accurate characterization can be achieved by resolving issues between GSC and NTGS correlation of stratigraphic units. New XRD data are also used to characterize the Hume-HRG contact (a drowning unconformity) in Kugaluk N-02 well of northern Anderson Plain.
Summary(Plain Language Summary, not published)
XRD surveys are important part of shale reservoir studies. New XRD results from 101 core samples of three wells mostly come from organic-rich mudrocks of the Horn River Group in the Canol shale play area. Available XRD database has a resolution for robust mineralogical characterization of stratigraphic units. The Canol Formation stands out by the highest quartz (81% median) and the lowest clay content (7% median). Clays in the HRG are dominated by illite. Carbonates: the Hare Indian and lower Canol are variously calcareous and dolomitic; the upper Canol is dolomitic and non-calcareous; basal Imperial shales are sideritic-dolomitic and non-calcareous. More accurate mineralogical characterization of mudrock units will be possible after resolving issues between GSC and NTGS correlation of formation contacts.
