Willamar West/Miocene/Unit #6 (API 42-489-00594) is a well in Willacy County operated by Pan American Petroleum Corp., completed June 1, 1965.
The RRC has issued 2 drilling permits between 1984 and 1986, permitted to 7,400 ft.
It was permitted by Amoco Production Company and has since transferred to Pan American Petroleum Corp. on the wellbore schedule.
Completion filings report 2 formation tops, including Willamar West Mio. 5000, Willamar West Mio. 5800.
Its lease has reported 475K barrels of oil and 663K mcf of gas since January 1993, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
