The RRC has issued 2 drilling permits between 1992 and 2017, permitted to 8,500 ft.
It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Tubb, L. Clearfork, Wichita-Albany.
Its 2 leases have reported 22.8M barrels of oil and 33.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 186 wells, so these are lease totals, not this well alone.
