WELLS · CROSS-SECTION
2 wells, subsea datum
West to east, 2.3 miles end to end. Depths are elevation minus measured depth, so tops line up regardless of surface terrain; a value above zero sits above sea level. Dashed lines join the same normalized formation in neighboring wells; nothing is interpolated. Where tops come from →

About this data
Formation tops and elevations from the RRC dbf900 wellbore file (completion filings), names normalized to the formations registry; well identity and location from the permit record. Subsea is elevation minus measured depth. Nothing between filed tops is estimated.
