Hufnall #1
Terry County · Suntura (Lower Clear Fork) field · Producing · Vertical
Hufnall #1 (API 42-445-31977) is a well in Terry County operated by Stanolind Permian LLC, completed February 25, 2002 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 30, 2001, permitted to 9,000 ft.
It was permitted by Gruy Petroleum Management CO. and has since transferred to Stanolind Permian LLC on the wellbore schedule.
Completion filings report one formation top, including Clear Fork.
Its lease has reported 611K barrels of oil and 107K mcf of gas since February 2002, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
