Regional [[cross section]]s are critical for all interpretations in an exploration play. Regional cross sections establish the correlations that structural, facies tract, and paleogeographic mapping is based on. They show stratigraphic patterns like [[Depocenter#Sediment_supply_rate_and_facies_patterns|progradation]].

The scale should generally be [[distance::100 mi]] or more, and a grid of [[strike]] and [[dip]] sections should be made. Use all data that would aid in correlations, and show stratigraphic patterns including well data (logs, cuttings, and cores), seismic sections, and outcrop data.
