[[:file:formation-fluid-pressure-and-its-application_fig5-26.png|Figure 1]] is an example of a subregional compartment contained within the regional pressure compartment of the Anadarko basin of Figure 5-25.

The fluids in a porous bioherm completely encased in shale (as shown in [[:file:formation-fluid-pressure-and-its-application_fig5-27.png|Figure 2]]) are virtually isolated from the nearby fluid systems outside the bioherm. The bioherm, then, is a pressure compartment that may or may not be abnormally pressured. Other geological features that may form local pressure compartments are fault blocks, sand lenses, and sand wedges developed in growth faults.
