Winkler County · Emperor (Holt) field · Vertical
Halley S. M. -B- #31 (API 42-495-31212) is a plugged well in Winkler County, plugged September 15, 2011, last operated by Basin Oil & Gas Operating LLC.
The RRC has issued one drilling permit, issued July 16, 1980, permitted to 4,950 ft.
It was permitted by Sun Expl. & Prod. CO.-Midland and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.
Its lease has reported 697K barrels of oil and 851K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 24 wells, so these are lease totals, not this well alone.
