Shut in

Crane County · Sand Hills (Tubb) field · Shut In · Vertical

Sand Hills Tubb Unit #200 (API 42-103-03588) is a well in Crane County operated by Formentera Operations LLC, completed October 11, 1991 and listed as shut in on the RRC schedule, shut in September 1, 2026.

The RRC has issued one drilling permit, issued November 18, 2022, permitted to 4,593 ft.

It was permitted by Slant Operating, LLC and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its lease has reported 2.15M barrels of oil and 4.23M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 80 wells, so these are lease totals, not this well alone.
