Windham 4h #2 (API 42-461-32419) is a well in Upton County operated by Diamondback E&P LLC, completed September 24, 1985 and listed as shut in on the RRC schedule, shut in February 1, 2016.
The RRC has issued one drilling permit, issued June 20, 1985, permitted to 9,275 ft.
It was permitted by Henry Petroleum Corp. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Jo Mill, Dean.
Its lease has reported 266K barrels of oil and 614K mcf of gas since January 1993, last reporting volume in June 2025. The lease carries 9 wells, so these are lease totals, not this well alone.
