Winkler County · Keystone (Colby) field · Shut In · Vertical
Walton J. B. A/C 2 #310 (API 42-495-30178) is a well in Winkler County operated by Formentera Operations LLC, completed February 5, 1972 and listed as shut in on the RRC schedule, shut in February 1, 2016.
The RRC has issued one drilling permit, issued October 30, 1997, permitted to 3,450 ft.
It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report one formation top, including Yates.
Its 2 leases have reported 771K barrels of oil and 941K mcf of gas since January 1993, last reporting in July 2026. The leases carry 57 wells, so these are lease totals, not this well alone.
