Bukowski-Bienski Unit #1RE
Brazos County · Giddings (Buda) field · Horizontal · Sidetrack
Bukowski-Bienski Unit #1RE (API 42-041-31550) is a plugged horizontal well in Brazos County, plugged September 28, 2022, last operated by Wildfire Energy Operating LLC.
The RRC has issued 2 drilling permits (amended once) between 1991 and 2000, 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 5 formation tops, including Midway, Navarro, Pecan Gap, Austin Chalk.
Its 2 leases have reported 145K barrels of oil and 503K 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.
