Halley S. M. -B- #23 (API 42-495-05394) is a well in Winkler County operated by Basin Oil & Gas Operating LLC, completed March 23, 1988.
The RRC has issued 2 drilling permits between 1988 and 1997, permitted to 11,325 ft.
It was permitted by Oryx Energy Company and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Clear Fork, Emperor (Wolfcamp).
Its 2 leases have reported 87K barrels of oil and 948K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
