The RRC has issued 2 drilling permits (amended twice) between 1989 and 2018, permitted to 9,380 ft.
It was permitted by Oxy USA Inc. and has since transferred to Oxy USA Eor LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Canyon, Strawn, Atoka, Barnett.
Its 2 leases have reported 15.7M barrels of oil and 974M mcf of gas since January 1993, last reporting in July 2026. The leases carry 358 wells, so these are lease totals, not this well alone.
