Stratigraphic trap geometries can be mapped and defined at any geologic scale from an interpretation of fades in seismic or well data, but diagenetic overprints often modify primary trapping geometries. Diagenetic changes often can be predicted and mapped reliably, especially if they follow fades or paleostructure. However, if diagenesis does not follow fades or paleostructure, then the exploration and exploitation risk increases because predicting the trap location is more difficult.
==Example==
Access to core, samples, and modern wireline log suites greatly facilitates subsurface interpretation. In the example below, both lateral and top seals in the dolomite reservoir were created by anhydrite cementation during early diagenesis. Primary fades changes do not control the location of the trap.
