FORMATIONS · RRC WELLBORE FILE

Reklaw

Reported as a top in 7,037 wells across 33 counties, at a median depth of 3,761 ft (1,997 to 5,345 ft in most wells). 543 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 →
