Capitan

Reported as a top in 152 wells across 7 counties, at a median depth of 3,482 ft (2,804 to 4,806 ft in most wells). 23 of those wells were permitted in the last three years.

A well counts if any of its completion filings report this formation, whether it produces from it or drilled through it. Depths are measured depth as filed; typo depths exist, which is why ranges are percentiles, not extremes. About completion reports →
