Gubbels Mary Mrs. #20 (API 42-157-31251) is a well in Fort Bend County operated by P.O.&G. Operating LLC, completed October 24, 1996.

The RRC has issued one drilling permit, issued October 6, 1981, permitted to 5,950 ft.

It was permitted by Exxon Corp. and has since transferred to P.O.&G. Operating LLC on the wellbore schedule.

Its lease has reported 960K barrels of oil and 830K mcf of gas since January 1993, last reporting in July 2026. The lease carries 17 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.
