Ector County · Harper (Devonian) field · Producing · Vertical
Harper Devonian Unit #3 (API 42-135-10217) is a well in Ector County operated by Hilcorp Energy Company, completed June 17, 1992 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 14, 2000, permitted to 12,085 ft.
It was permitted by Oxy USA Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 4 leases have reported 2.99M barrels of oil and 16.7M mcf of gas since January 1993, last reporting in July 2026. The leases carry 54 wells, so these are lease totals, not this well alone.
