[[Stratigraphic trap]] geometries can be mapped and defined at any geologic scale from an interpretation of [[facies]] in [[Seismic data|seismic]] or well data (see [[Basic open hole tools]] and [[Basic cased hole tools]]), but [[Diagenesis|diagenetic]] overprints often modify primary [[Trap|trapping geometries]]. Diagenetic changes often can be predicted and mapped reliably, especially if they follow facies or paleostructure. However, if diagenesis does not follow facies or paleostructure, then the exploration and exploitation risk increases because predicting the trap location is more difficult.
