Headlee Devonian Unit #3907 (API 42-329-01917) is a plugged well in Midland County, plugged September 20, 2022, last operated by Chevron U. S. A. Inc..
The RRC has issued 2 drilling permits between 1989 and 2004, permitted to 13,082 ft.
It was permitted by Four Star Oil And Gas Company and has since transferred to Chevron U. S. A. Inc. on the wellbore schedule.
Completion filings report 8 formation tops, including Anhydrite & Salt, Yates, San Andres, Dolomite & Anhydrite.
Its 4 leases have reported 175K barrels of oil and 2.74M mcf of gas since January 1993, last reporting in July 2026. The leases carry 29 wells, so these are lease totals, not this well alone.
