Mikulenka V.L. Oil Unit #1 (API 42-285-31994) is a plugged well in Lavaca County, plugged November 3, 2025, last operated by Capital Star Oil & Gas Inc..
The RRC has issued 2 drilling permits (amended once) between 1987 and 1992, permitted to 11,000 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Capital Star Oil & Gas Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Wilcox, Eagle Ford, Edwards, Catahoula.
Its 4 leases have reported 59.3K barrels of oil and 104K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
