Mauerman -A- #R13 (API 42-029-31846) is a plugged well in Bexar County, plugged April 1, 2026, last operated by South Sam Operating Company LLC.
The RRC has issued one drilling permit, issued November 12, 1981, permitted to 500 ft.
It was permitted by D & M Drilling and has since transferred to South Sam Operating Company LLC on the wellbore schedule.
Its lease has reported 94.5K barrels of oil and 142 mcf of gas since January 1993, last reporting volume in March 2026. The lease carries 289 wells, so these are lease totals, not this well alone.
