O Brien G. W. Etal #2011 (API 42-475-37846) is a well in Ward County operated by Sundown Energy LP, completed August 29, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 1, 2019, permitted to 12,000 ft.

It was permitted by Four Corners Petroleum II, LLC and has since transferred to Sundown Energy LP on the wellbore schedule.

Completion filings report 10 formation tops, including Rustler, Yates, Seven Rivers, Queen.

Its lease has reported 3.03M barrels of oil and 7.17M mcf of gas since January 1993, last reporting in July 2026. The lease carries 40 wells, so these are lease totals, not this well alone.
