Tumlinson Unit #A3 (API 42-127-32683) is a plugged well in Dimmit County, plugged February 3, 2021, last operated by Texowa LLC.

The RRC has issued one drilling permit, issued July 24, 1985, permitted to 4,900 ft.

It was permitted by Cabot Petroleum Corporation and has since transferred to Texowa LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Escondido, Navarro, Olmos.

Its lease has reported 4.59K barrels of oil and 80.4K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 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.
