Williamson Iona #4A (API 42-415-02696) is a well in Scurry County operated by Crossroads Operating LLC, completed November 17, 2000 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1985 and 2001, permitted to 3,270 ft.
It was permitted by Anadarko Petroleum Corp. and has since transferred to Crossroads Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including San Andres, Glorieta.
Its 3 leases have reported 356K barrels of oil and 34.8K mcf of gas since January 1993, last reporting in July 2026. The leases carry 33 wells, so these are lease totals, not this well alone.
