Good reservoir properties are seen in the vuggy packstone facies, congruent with the observed pore geometries. Permeabilities in rock with only 10% porosity are as high as 10 md.

[[:file:predicting-reservoir-system-quality-and-performance_fig9-102.png|Figure 1]] is a crossplot of routine core porosity and [[permeability]] from Midale in an example well at Weyburn field. The diagonal lines are contours of equal r<sub>35</sub> values. On the plot, vuggy packstone facies (group A; data points 3, 4, 6, and 8) are characterized by lower porosity but higher permeability.
