Wichita County · Wichita County Regular field · Producing · Vertical
Huff #16 (API 42-485-40307) is a well in Wichita County operated by 4j Oil CO. LLC, completed September 9, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 28, 1985, permitted to 750 ft.
It was permitted by Cmz Investments, Inc. and has since transferred to 4j Oil CO. LLC on the wellbore schedule.
Completion filings report one formation top, including Cisco.
Its lease has reported 6.79K barrels of oil and 93 mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
Operator of record
