FIGURE 13 The results of the spot-minipermeametry testing on two examples (Sample 1 location
Alberta, 06-31-14-01W4, 507.65 m depth; and Sample 2 location Alberta, 0606-31-14-01W4,
509.00 m depth). On the left, the core photographs are annotated with test locations and their cor-
responding permeability measurements in millidarcy (mD). On the right, contour plots highlight the
distribution of permeability. The data points are arranged using 1-cm grid spacing. Gaps in the data
set represent discarded measurements resulting from a poor probe-tip seal.
