Thornberry -K- #4 (API 42-003-36616) is a well in Andrews County operated by Crescent Energy Operating LLC, completed October 21, 2022 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued January 4, 1990, permitted to 4,800 ft.

It was permitted by Royale Operating Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Queen, Grayburg, San Andres.

Its lease has reported 163K barrels of oil and 119K mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 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.
