Willis 44 #5 (API 42-329-31590) is a plugged well in Midland County, plugged August 21, 2014, last operated by Diamondback E&P LLC.
The RRC has issued 2 drilling permits between 1985 and 2002, permitted to 12,000 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.
Its 2 leases have reported 423K barrels of oil and 1.98M mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
