Walton J.B. A #8 (API 42-495-04483) is a well in Winkler County operated by Xto Energy Inc., completed May 18, 2011.
The RRC has issued 2 drilling permits between 1986 and 2011, permitted to 10,034 ft.
It was permitted by Bopco, L.P. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report 10 formation tops, including T/ Anhydrite, T/Anhydrite, B/ Permian, B/Permian.
Its 3 leases have reported 385K barrels of oil and 7.78M 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.
