FORMATIONS · RRC WELLBORE FILE
Pecan Gap
Reported as a top in 8,082 wells across 73 counties, at a median depth of 6,951 ft (1,915 to 12,008 ft in most wells). 307 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 →
