Keystone Cattle Company #6
Winkler County · Keystone SW. (San Andres) field · Vertical
Keystone Cattle Company #6 (API 42-495-31408) is a well in Winkler County operated by Formentera Operations LLC, completed March 11, 1992.
The RRC has issued 2 drilling permits between 1981 and 1992, permitted to 4,808 ft.
It was permitted by Wood, Mcshane & Thams and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Colby, San Andres.
Its 3 leases have reported 271K barrels of oil and 957K mcf of gas since January 1993, last reporting in July 2026. The leases carry 13 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
