Explanation
Black Wells-Lower Cretaceous Thickness
White Wells-Lower Cretaceous zero thickness in subsurface
Red Wells-Spudding in sub-Lower Cretaceous
Gray Wells-Lower Cretaceous penetrations, no impact in mapping
Yellow Wells-Lower Cretaceous penetrations, judged to and caused to have impact in mapping
Reddish pattern indicates sub lower Cretaceous Outcrop, used to constrain mapping
