Keystone Cattle Company #359 (API 42-495-31545) is a well in Winkler County operated by Basin Oil & Gas Operating LLC, completed February 7, 1983 and listed as shut in on the RRC schedule, shut in November 1, 2021.
The RRC has issued one drilling permit, issued December 15, 1982, permitted to 4,520 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its lease has reported 450K barrels of oil and 2.76M mcf of gas since January 1993, last reporting volume in March 2026. The lease carries 28 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 4, 2012. Density, Neutron. 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.
