FORMATIONS · RRC WELLBORE FILE

Nacatoch

Reported as a top in 3,494 wells across 42 counties, at a median depth of 1,550 ft (800 to 2,979 ft in most wells). 258 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 →
