Winkler County · Halley field · Shut In · Vertical
Halley S. M. #601 (API 42-495-33041) is a well in Winkler County operated by Team Operating L.L.C., completed July 18, 2005 and listed as shut in on the RRC schedule, shut in November 1, 2019.
The RRC has issued one drilling permit, issued May 23, 2005, permitted to 3,000 ft.
It was permitted by Southwest Royalties, Inc. and has since transferred to Team Operating L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Tansil, Yates, Seven Rivers.
Its lease has reported 1M barrels of oil and 4.17M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 256 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Aug 1, 2006. Density, Gamma ray, Neutron, Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
