In [[:file:predicting-reservoir-system-quality-and-performance_fig9-25.png|Figure 2]], flow unit 1 is a sucrosic dolomite. On a face of a plug of flow unit 1, a very large number of very small pore throats (capillaries) occur, resulting in a measurable flow (Q). That Q, at a measured cross-sectional area A of the plug, yields a K<sub>a</sub> of approximately 20 md. | In [[:file:predicting-reservoir-system-quality-and-performance_fig9-25.png|Figure 2]], flow unit 1 is a sucrosic dolomite.
