Buchanan 35 #1X (API 42-329-31025) is a plugged well in Midland County, plugged October 23, 2013, last operated by Diamondback E&P LLC.
The RRC has issued 2 drilling permits between 1981 and 1998, permitted to 9,000 ft.
It was permitted by Cox, John L. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Redbeds, Spraberry, Dean.
Its lease has reported 73.6K barrels of oil and 185K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
