Correlation sections that will be used for establishing sandstone body geometry should have a depositionally flat datum (such as a [[bentonit]]e bed, marine shale bed, or laterally persistent limestone). Sections should be oriented parallel and perpendicular to depositional [[strike]], if known, and represent as straight a line as possible given well density and placement. | Correlation sections that will be used for establishing sandstone body geometry should have a depositionally flat datum (such as a [[bentonit]]e bed, marine shale bed, or laterally persistent limestone).
