Castile

Reported as a top in 3,520 wells across 7 counties, at a median depth of 2,581 ft (999 to 3,880 ft in most wells). 290 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 →
