Terry I. W. #12 (API 42-431-31040) is a well in Sterling County operated by Union Pacific Resources Company, completed November 6, 1981.
The RRC has issued 2 drilling permits between 1981 and 2001, permitted to 8,800 ft.
It was permitted by Rme Petroleum Company and has since transferred to Union Pacific Resources Company on the wellbore schedule.
Its 3 leases have reported 205K barrels of oil and 1.99M mcf of gas since January 1993, last reporting in July 2026. The leases carry 25 wells, so these are lease totals, not this well alone.
