Willacy County · Willamar W.(miocene 6400) field · Producing · Vertical
Willamar West Miocene Unit #M17 (API 42-489-30735) is a well in Willacy County operated by Citation Oil & Gas Corp., completed June 2, 1984 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 18, 1983, permitted to 6,800 ft.
It was permitted by Amoco Production Company and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.
Completion filings report one formation top, including Miocene (undifferentiated).
Its lease has reported 229K barrels of oil and 262K mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
