Tamu #4
Burleson County · Giddings (Austin Chalk-3) field · Horizontal
Tamu #4 (API 42-051-33287) is a horizontal well in Burleson County operated by Wildfire Energy Operating LLC, completed January 26, 1992.
The RRC has issued 2 drilling permits (amended twice) between 1991 and 2001, permitted to 16,000 ft.
It was permitted by Apache Corporation and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Austin Chalk, Buda.
Its 2 leases have reported 1.06M barrels of oil and 12.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
Operator of record
