Little Virginia L. #5A (API 42-163-32423) is a well in Frio County operated by Bigfoot Oil LLC, completed May 21, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 23, 1985, permitted to 4,000 ft.
It was permitted by Ancira, Robert and has since transferred to Bigfoot Oil LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Cz-Wil, Midway, Navarro.
Its lease has reported 274K barrels of oil and 35 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
