Three Bar Unit #37 (API 42-003-05939) is a well in Andrews County operated by Hilcorp Energy Company, completed November 11, 2015.
The RRC has issued one drilling permit, issued September 26, 2017, permitted to 8,266 ft.
It was permitted by Apache Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 7 formation tops, including Rustler, Yates, Grayburg, Clear Fork.
Its 2 leases have reported 8.66M barrels of oil and 17.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 106 wells, so these are lease totals, not this well alone.
