Regional stratigraphic well-log [[cross section]]s form the foundation for many basin studies. They give a regional view of basin stratigraphy and can be integrated with seismic and biostratigraphic data. The list below outlines the steps for building regional well-log cross sections.

# Build a grid of well-log sections that crosses the entire basin, either along depositional dip or depositional strike. Use as many wells as practical. Where available, add measured sections and [[core description]]s to the grid.

# Correlate cross sections. Look for [[Unconformity|unconformities]] and flooding surfaces.
