Isensee #3 (API 42-355-33965) is a well in Nueces County operated by Basin Oil & Gas Operating LLC, completed March 11, 2021.

The RRC has issued 2 drilling permits (amended once) between 2009 and 2020, permitted to 15,000 ft.

It was permitted by Great Western Drilling Company and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Minocene - Fleming (Lagarto-Oakv, Miocene (undifferentiated), Catahoula, Greta.

Its 3 leases have reported 147K barrels of oil and 105K mcf of gas since February 2010, last reporting in July 2026. The leases carry 4 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.
