Stefka-Stefka Unit #1RE
Burleson County · Giddings (Austin Chalk-3) field · Producing · Horizontal
Stefka-Stefka Unit #1RE (API 42-051-33050) is a horizontal well in Burleson County operated by Wildfire Energy Operating LLC, completed May 25, 1990 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1990 and 2010, permitted to 7,156 ft.
It was permitted by Anadarko E&P Company LP and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Midway, Navarro, Taylor, Pecan Gap.
Its lease has reported 133K barrels of oil and 125K 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.
