FORMATIONS · RRC WELLBORE FILE

Bossier

Reported as a top in 9,149 wells across 34 counties, at a median depth of 11,131 ft (9,813 to 12,594 ft in most wells). 203 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 →
