Variations in pore geometry have the expected effect on log responses and water saturations (S<sub>w</sub>). The Midale Vuggy in a cored field well consists of interbeds of packstone and mudstone. [[:file:predicting-reservoir-system-quality-and-performance_fig9-103.png|Figure 1]] is a Pickett plot for the Midale Vuggy from an example well in Weyburn field. Data points cluster around higher resistivities for packstones (group A) and lower resistivities for mudstones (group B), reflecting the higher water saturations of the mudstones.
