FORMATIONS · RRC WELLBORE FILE

BMA

Reported as a top in 5,201 wells across 35 counties, at a median depth of 6,626 ft (4,952 to 7,880 ft in most wells). 74 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 →
