Caribou Unit #1 (API 42-395-30560) is a horizontal well in Robertson County operated by Wildfire Energy Operating LLC, completed April 25, 1998 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 4, 1998, permitted to 11,685 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Bentonite, Austin Chalk, Eagle Ford, Buda.
Its 2 leases have reported 95.8K barrels of oil and 65.2K mcf of gas since April 1998, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
