Sand Hills Judkins Unit #23 (API 42-103-03610) is a well in Crane County operated by Formentera Operations LLC, completed April 1, 1981 and listed as temp abandoned on the RRC schedule, shut in August 1, 2010.

The RRC has issued one drilling permit, issued February 2, 1981, permitted to 3,420 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its 2 leases have reported 4.13K barrels of oil and 451K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
