Thornberry-Lzs #1 (API 42-003-32239) is a plugged well in Andrews County, plugged October 9, 2012, last operated by Crescent Energy Operating LLC.
The RRC has issued one drilling permit, issued March 5, 1980, permitted to 4,900 ft.
It was permitted by Rankin Oil CO. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including T. Anhydrite, Yates, San Andres.
Its lease has reported 381K barrels of oil and 205K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 33 wells, so these are lease totals, not this well alone.
