Colorado County · Columbus (Consolidated) field · Producing · Vertical
Columbus Field Unit #1021 (API 42-089-31810) is a well in Colorado County operated by Rusk Energy Operating LLC, completed August 22, 1997 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits (amended once) between 1990 and 1997, permitted to 9,910 ft.
It was permitted by Oxy USA Inc. and has since transferred to Rusk Energy Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Wilcox, Columbus (7-A), Columbus 7-A, Columbus (11-E).
Its 4 leases have reported 1.68M barrels of oil and 5.29M mcf of gas since January 1993, last reporting in July 2026. The leases carry 72 wells, so these are lease totals, not this well alone.
