Mauerman #AA21 (API 42-029-37545) is a well in Bexar County operated by South Sam Operating Company LLC, completed June 19, 1986 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 23, 1986, permitted to 500 ft.

It was permitted by Akm Company and has since transferred to South Sam Operating Company LLC on the wellbore schedule.

Its lease has reported 109K barrels of oil and 143 mcf of gas since January 1993, last reporting in July 2026. The lease carries 226 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.
