Willamar West Miocene Unit #11 (API 42-489-00258) is a plugged well in Willacy County, plugged October 18, 2006, last operated by Amoco Production Company.
The RRC has issued 4 drilling permits between 1981 and 1994, permitted to 8,056 ft.
It was permitted by Citation Oil & Gas Corp. and has since transferred to Amoco Production Company on the wellbore schedule.
Its 2 leases have reported 21.6K barrels of oil and 369K mcf of gas since January 1993, last reporting in December 2012. The leases carry 5 wells, so these are lease totals, not this well alone.
