Lenz Unit #1RE
Brazos County · Giddings (Buda) field · Horizontal · Sidetrack
Lenz Unit #1RE (API 42-041-31580) is a plugged horizontal well in Brazos County, plugged March 26, 2026, last operated by Wildfire Energy Operating LLC.
The RRC has issued 2 drilling permits (amended once) between 1992 and 1999, permitted to 14,000 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Pecan Gap, Austin Chalk, Lower Cretaceous, Buda.
Its 2 leases have reported 250K barrels of oil and 995K 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.
