Judkins Gas Unit I #4
Crane County · Sand Hills (Judkins) field · Producing · Vertical
Judkins Gas Unit I #4 (API 42-103-04576) is a well in Crane County operated by Formentera Operations LLC, completed August 24, 1978 and listed as producing on the RRC schedule, shut in March 1, 2026.
The RRC has issued one drilling permit, issued July 19, 1978, permitted to 4,520 ft.
It was permitted by Samedan Oil Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Its 3 leases have reported 87.4K barrels of oil and 1.58M mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
