FORMATIONS · RRC WELLBORE FILE

Smackover

Reported as a top in 291 wells across 27 counties, at a median depth of 11,325 ft (8,572 to 13,080 ft in most wells). 6 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 →
