Harper Devonian Unit #2 (API 42-135-01941) is a plugged well in Ector County, plugged January 11, 1996, last operated by Hilcorp Energy Company.
The RRC has issued 2 drilling permits between 1978 and 1985, permitted to 12,467 ft.
It was permitted by Union Texas Petroleum Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 2.68M barrels of oil and 16.4M mcf of gas since January 1993, last reporting in July 2026. The leases carry 46 wells, so these are lease totals, not this well alone.
