Tetens A #4 (API 42-165-35648) is a well in Gaines County operated by Free Rein Operating LLC, completed January 21, 2001 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 27, 2000, permitted to 5,200 ft.

It was permitted by Aroc (Texas) Inc. and has since transferred to Free Rein Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, Seven Rivers, Queen, San Andres.

Its lease has reported 766K barrels of oil and 37.9K mcf of gas since February 1998, last reporting in July 2026. The lease carries 7 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.
