Yates

Reported as a top in 67,962 wells across 42 counties, at a median depth of 2,568 ft (1,250 to 3,046 ft in most wells). 5,456 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 →
