The RRC has issued 2 drilling permits between 1981 and 1995, permitted to 9,309 ft.

It was permitted by Union Oil Company Of California and has since transferred to Morningstar Operating LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Grayburg, San Andres, Wolfcamp, Pennsylvanian.

Its 3 leases have reported 5.46M barrels of oil and 8.94M mcf of gas since January 1993, last reporting in July 2026. The leases carry 207 wells, so these are lease totals, not this well alone.
