Falls City Unit #1312 (API 42-255-00010) is a well in Karnes County operated by Britanco L.L.C., completed December 18, 1984 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits in 1984, permitted to 6,060 ft.
It was permitted by Sun Expl. & Prod. CO.-Corpus and has since transferred to Britanco L.L.C. on the wellbore schedule.
Completion filings report 2 formation tops, including Lma, Lpa.
Its 2 leases have reported 98.3K barrels of oil and 3.24K mcf of gas since January 1993, last reporting in July 2026. The leases carry 29 wells, so these are lease totals, not this well alone.
