Midland County · Mid-Mar East (Fusselman) field · Vertical
Penrose-Oldham 27 #5 (API 42-329-31374) is a well in Midland County operated by Endeavor Energy Resources L.P., completed October 12, 1984.
The RRC has issued 3 drilling permits between 1984 and 2007, permitted to 12,000 ft.
It was permitted by Kemper Operating Company, Inc. and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.
Completion filings report 6 formation tops, including Strawn, Mississippian, Devonian, Fusselman.
Its 3 leases have reported 221K barrels of oil and 184K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
