Winkler County · Keystone (Colby) field · Shut In · Vertical
Walton J. B. A/C 2 #316 (API 42-495-32065) is a well in Winkler County operated by Formentera Operations LLC, completed March 5, 1987 and listed as shut in on the RRC schedule, shut in November 1, 2023.
The RRC has issued 2 drilling permits in 1986, permitted to 3,300 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Yates, Seven Rivers, Queen, Colby.
Its lease has reported 771K barrels of oil and 747K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 56 wells, so these are lease totals, not this well alone.
