The RRC has issued 2 drilling permits (amended once) between 1996 and 2001, permitted to 2,900 ft.

It was permitted by Union Oil Company Of California and has since transferred to Basa Resources Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Pecan Gap, Austin Chalk, Woodbine.

Its 2 leases have reported 1.07M barrels of oil and 972K mcf of gas since January 1993, last reporting in July 2026. The leases carry 18 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
