Maness

Reported as a top in 40 wells across 12 counties, at a median depth of 3,862 ft (3,600 to 10,233 ft in most wells). 0 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 →
