WELL · 42-477-30688 · DISTRICT 3
Yelderman-Bredthauer Unit #1
Washington County · Giddings (Austin Chalk Gas) field · Horizontal · Sidetrack
Yelderman-Bredthauer Unit #1 (API 42-477-30688) is a horizontal well in Washington County operated by Rme Petroleum Company, completed June 2, 1992.
The RRC has issued 2 drilling permits (amended twice) between 1991 and 2000, permitted to 16,000 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Rme Petroleum Company on the wellbore schedule.
Completion filings report 3 formation tops, including Austin Chalk, Bentonte, Eagle Ford.
Its 2 leases have reported 178K barrels of oil and 2.14M 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.
