FORMATIONS · RRC WELLBORE FILE

Bone Spring

Reported as a top in 13,667 wells across 10 counties, at a median depth of 7,955 ft (6,125 to 9,103 ft in most wells). 1,746 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 →
