Arco-Davis #1 (API 42-461-32408) is a plugged well in Upton County, plugged February 19, 2010, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued 2 drilling permits between 1985 and 1987, permitted to 10,600 ft.
It was permitted by Cox, John L. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Cretaceous, Spraberry, Dean, Pennsylvanian.
Its 2 leases have reported 68.7K barrels of oil and 243K mcf of gas since January 1993, last reporting in April 2025. The leases carry 3 wells, so these are lease totals, not this well alone.
