As shown on [[:File:Predicting-reservoir-system-quality-and-performance fig9-102.png|Figure 2]], mudstones (B) are [[Wikipedia:Microporous material|micro]]- to [[Wikipedia:Mesoporous material|mesoporous]]; packstones (A) are meso- to [ http://en.wiktionary.org/wiki/macroporous macroporous]. The mudstones have more pores with smaller pore throats than the packstones. This means mudstones have greater pore surface area and higher immobile S_w. As a consequence, S_w values for mudstones are higher at any given elevation in the oil column.

[[:file:predicting-reservoir-system-quality-and-performance_fig9-104.png|Figure 3]] is a [[Buckles plot]] for the Weyburn well. The hyperbolic curves represent equal values of S_w × porosity (Φ). Points from the same pore type that fall along a hyperbolic curve are at immobile S_w. Curves with higher values represent higher immobile S_w.
