Jack County · KRS (Marble Falls) field · Shut IN · Vertical
Wilhelm #N 4 (API 42-237-40177) is a well in Jack County operated by FX Energy Operating LLC, completed March 20, 2015 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 7, 2014, permitted to 7,000 ft.
It was permitted by Newark E&P Operating, LLC and has since transferred to FX Energy Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Atoka, Bryson, Butram, Caddo.
Its lease has reported 35.5K barrels of oil and 858K mcf of gas since April 2013, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
