Darlene Unit #8HS
Karnes County · Eagleville (Eagle Ford-2) field · Producing · Horizontal
Darlene Unit #8HS (API 42-255-37230) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed January 10, 2022 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 21, 2021, permitted to 14,000 ft.
It was permitted by Validus Nrg Aquilas Assetco LLC and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Queen City, Reklaw, Carrizo.
Its lease has reported 1.1M barrels of oil and 1.22M mcf of gas since December 2010, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
