Mauermann #111Y (API 42-029-36743) is a well in Bexar County operated by South Sam Operating Company LLC, completed November 6, 1985 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 7, 1985, permitted to 500 ft.

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

Its lease has reported 41.1K barrels of oil and 132 mcf of gas since January 1993, last reporting in July 2026. The lease carries 141 wells, so these are lease totals, not this well alone.
