R. D. Tucker Unit #1 (API 42-177-31798) is a plugged horizontal well in Gonzales County, plugged September 8, 1993, last operated by Modern Exploration Inc..
The RRC has issued 2 drilling permits (amended once) between 1990 and 2008, permitted to 10,800 ft.
It was permitted by Lucas Energy, Inc. and has since transferred to Modern Exploration Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Carrizo, Wilcox, Taylor, Anacasho.
Its 2 leases have reported 38 barrels of oil and 4 mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 1.94M barrels injected in the 12 months reported through November 2025.
