2 wells, subsea datum

West to east, 0.4 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. Each formation filed in more than one well has its own color, joined between neighboring wells and shaded down to the next formation both filed; 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 from the permit record, location from the shared well record. Subsea is elevation minus measured depth. Nothing between filed tops is estimated.
