Sebesta Lydia Unit #1 (API 42-051-31429) is a plugged well in Burleson County, plugged April 20, 1993, last operated by Wildfire Energy Operating LLC.
The RRC has issued 2 drilling permits between 1981 and 1989, permitted to 8,350 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 6 formation tops, including Pacan Gap, Austin Chalk, Eagle Ford, False Buda.
Its lease has reported 314K barrels of oil and 637K mcf of gas since January 1993, last reporting volume in March 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
