Duvalle #1 (API 42-143-31026) is a well in Erath County operated by United Operating LLC, completed June 26, 2002.
The RRC has issued one drilling permit (amended once), issued May 16, 2002, permitted to 4,000 ft.
It was permitted by Richman Petroleum Corp. and has since transferred to United Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Duffer, Caddo, Marble Falls, Barnett.
Its 2 leases have reported 387 barrels of oil and 11K mcf of gas since June 2002, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
