Epley L. B. #8 (API 42-329-31571) is a well in Midland County operated by EP Operating Limited Partnership, completed September 29, 1988.
The RRC has issued 2 drilling permits between 1985 and 1988, permitted to 12,200 ft.
It was permitted by EP Operating Company and has since transferred to EP Operating Limited Partnership on the wellbore schedule.
Completion filings report 8 formation tops, including Grayburg, San Andres, Spraberry, Wolfcamp.
Its 3 leases have reported 525K barrels of oil and 1.18M mcf of gas since January 1993, last reporting in July 2026. The leases carry 19 wells, so these are lease totals, not this well alone.
