Examples of field studies that apply the flow unit concept are listed in Table 1. A larger number of studies have identified and mapped lithofacies control on geometry and petrophysical properties of reservoirs but have not applied a flow unit classification to these subdivisions. Some examples are listed in Table 2 and illustrated in [[:file:flow-units-for-reservoir-characterization_fig2.png|Figure 2]]. These studies are good examples of the stratigraphic and sedimentological component of the process of flow unit subdivision.
