Hillger Alton #1
Glasscock County · Cobra (Wolfcamp) field · Horizontal
Hillger Alton #1 (API 42-173-32812) is a horizontal well in Glasscock County operated by Fed Operating LLC, completed February 20, 1998.
The RRC has issued one drilling permit (amended twice), issued September 5, 1997, permitted to 7,950 ft.
It was permitted by Dyad Petroleum Company and has since transferred to Fed Operating LLC on the wellbore schedule.
Its 2 leases have reported 60.5K barrels of oil and 106K mcf of gas since February 1998, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
