Winkler County · Kermit field · Shut In · Vertical

Walton J. B. #318 (API 42-495-32069) is a well in Winkler County operated by Formentera Operations LLC, completed June 30, 1987 and listed as shut in on the RRC schedule, shut in November 1, 2025.

The RRC has issued 3 drilling permits between 1986 and 1987, permitted to 3,470 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 Tansil, Tansill, Yates, Seven Rivers.

Its lease has reported 257K barrels of oil and 402K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 43 wells, so these are lease totals, not this well alone.
