Shivers J. R. 12 #11 (API 42-467-30749) is a well in Van Zandt County operated by Basa Resources Inc., completed April 27, 1994 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended once) between 1989 and 1994, permitted to 2,950 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 4 formation tops, including Nacatoch, Pecan Gap, Austin Chalk, Woodbine.

Its 2 leases have reported 592K barrels of oil and 784K mcf of gas since January 1993, last reporting in July 2026. The leases carry 16 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.
