Summary

Hydraulic testing has revealed dramatic underpressures in Paleozoic shales and carbonates at the Bruce nuclear site in Ontario. Although evidence from both laboratory and field studies suggests that a small amount of gas phase methane could be present in the shale, previous studies examining causal linkages between gas phase and the underpressure have been inconclusive. To better elucidate processes in such a system, we used a highly simplified 1-D representation of the site to test, using iTOUGH2-EOS7C, the effects of various factors on the evolution of gas phase methane and pressures within the system. Heterogeneity was represented using three stratigraphic regions with distinctly different capillary pressure characteristics and, [...]

Purpose

This groundwater model was created to examine possible linkages between multiphase methane evolution and pressure distribution within the subsurface of a site where a potential deep geologic repository for low- and intermediate-level nuclear waste has been proposed. The data used to create the model are available on the Ontario Power Generation website (https://www.opg.com/generating-power/nuclear/nuclear-waste-management/Deep-Geologic-Repository/Pages/Project-Development.aspx).
