Willamar West Unit #165 (API 42-489-30765) is a well in Willacy County operated by Citation Oil & Gas Corp., completed July 28, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 26, 1984, permitted to 8,050 ft.
It was permitted by Amoco Production Company and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.
Completion filings report 4 formation tops, including Marg Frio 1, Marg Frio 2, Marg Frio 3, Marg Frio 4.
Its lease has reported 3.04M barrels of oil and 3.18M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 207 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
