Rock quality is easily characterized using r<sub>35</sub>. Consider the clusters of points representing flow units 1 and 2 ([[:file:predicting-reservoir-system-quality-and-performance_fig9-16.png|Figure 1]]) on the K<sub>a</sub>/Φ plot in [[:file:predicting-reservoir-system-quality-and-performance_fig9-19.png|Figure 4]]. The diagonal curved lines represent equal r<sub>35</sub> values. Points plotting along the same lines represent rocks with similar r<sub>35</sub> values and have similar quality. By interpolation, r<sub>35</sub> for flow unit 1 is approximately 1.1μ, and r<sub>35</sub> for flow unit 2 is approximately 3μ. The r<sub>35</sub> in flow unit 2 is almost three times as large as flow unit 1. Therefore, flow unit 2 has better flow quality.
