iTOUGH2-EOS7C model used to analyze multiphase flow and hydromechanical coupling in underpressured shale at the Bruce Nuclear Site, Ontario, Canada
July 11, 2019
Using iTOUGH2-EOS7C, a simple 1-D model was developed to represent a site in Ontario, Canada which is being considered
for nuclear waste disposal. The site exhibits substantially underpressured water and potential evidence for gas phase methane
within a thick section of sedimentary rocks. To investigate possible mechanisms for the development of the underpressure in a
multiphase system, hydromechanical coupling during a glacial cycle was simulated with and without gas phase methane present.
Results indicate that, while the gas dampened the effects of the loading cycle, it did not preclude underpressure development.
This USGS data release contains all of the input and output files for the simulations described in the associated journal article.

Glacially-induced hydromechanical coupling in shale may have caused underpressured water in the eastern Michigan Basin despite the possible presence of gas phase methane
When glacial cycles occur above low-permeability geologic formations, such as the shale and limestone units being considered for nuclear waste disposal in Canada, pressures may differ greatly from normal hydrostatic conditions. Although shale also often has the propensity to generate separate phase fluids like natural gas, it is largely uncertain how the processes that control this...
