Halley S. M. (One) #251 (API 42-495-30470) is a well in Winkler County operated by Wallace Operating Company LLC, completed September 29, 1976.

The RRC has issued one drilling permit, issued March 28, 1995, permitted to 2,835 ft.

It was permitted by Midland Southwest Cold Lake Inc and has since transferred to Wallace Operating Company LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, Seven Rivers, Colby, Queen.

Its 2 leases have reported 1.12M barrels of oil and 4.91M mcf of gas since January 1993, last reporting in July 2026. The leases carry 282 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
