Bexar County · Monksfield (350 Sand) field · Producing · Vertical
Mauerman #D2 (API 42-029-36122) is a well in Bexar County operated by South Sam Operating Company LLC, completed January 17, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 28, 1984, permitted to 400 ft.
It was permitted by R.D. Oil 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 volume in August 2025. The lease carries 226 wells, so these are lease totals, not this well alone.
