The stratigraphic cross section in [[:file:predicting-reservoir-system-quality-and-performance_fig9-5.png|Figure 4]] shows the facies and flow units present in the Hartzog Draw field of Wyoming. The producing formation is the Upper Cretaceous Shannon Sandstone, composed of fine- to medium-grained clayey and glauconitic sandstones deposited as marine shelf bars. Notice how facies and flow units do not always correspond, especially within the central bar facies. The flow units in this section of Hartzog Draw behave as a unit; therefore, only one container is present.
