Wilson County · Acleto Creek (Poth C) field · Vertical
Krell #4 (API 42-493-31398) is a plugged well in Wilson County, plugged March 20, 2017, last operated by Johanson Oil.
The RRC has issued one drilling permit, issued September 30, 1983, permitted to 2,990 ft.
It was permitted by Silver Falls Petroleum Corp. and has since transferred to Johanson Oil on the wellbore schedule.
Its 2 leases have reported 1.7K barrels of oil and 38 mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
