Dora Roberts Ranch Unit #410
Midland County · Dora Roberts (Pennsylvanian) field · Vertical
Dora Roberts Ranch Unit #410 (API 42-329-00437) is a plugged well in Midland County, plugged March 27, 1992, last operated by Oxy USA Inc..
The RRC has issued one drilling permit, issued March 4, 1986, permitted to 13,170 ft.
It was permitted by Cities Service Oil & Gas Corp. and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report one formation top, including Pennsylvanian.
Its lease has reported 26.2K barrels of oil and 837K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 18 wells, so these are lease totals, not this well alone.
