Crane County · Sand Hills (Wojcik-McElroy) field · Temp Abandoned · Vertical
Sand Hills Judkins Unit #46 (API 42-103-30451) is a well in Crane County operated by Formentera Operations LLC, completed March 9, 2005 and listed as temp abandoned on the RRC schedule, shut in June 1, 2020.
The RRC has issued 2 drilling permits between 1990 and 2005, permitted to 4,850 ft.
It was permitted by Encore Operating, L.P. and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Wojcik-Mcelroy, Judkins, Tubb.
Its 3 leases have reported 2.17M barrels of oil and 4.67M mcf of gas since January 1993, last reporting in July 2026. The leases carry 85 wells, so these are lease totals, not this well alone.
