FORMATIONS · RRC WELLBORE FILE

Cleveland

Reported as a top in 5,018 wells across 12 counties, at a median depth of 7,718 ft (6,680 to 10,298 ft in most wells). 40 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 →
