    dct:description """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, in one case, a few thin, distinct zones. Underpressure 
occurred only when gas pressures set as an initial conditions required it, and even in this case it was 
geologically short-lived. We conclude that the presence of multiple fluid phases is unlikely to explain 
the underpressure at the site, and suggest that the influence of gas phase methane on pore water flow 
is minimal. This is consistent with prior conceptualizations of the underpressured section as a thick 
aquiclude, in which solute transport occurs extremely slowly, bounded by aquifers of significantly higher 
permeability. """ ;
