Dorn #4 (API 42-335-34203) is a well in Mitchell County operated by Nordstrand Engineering Inc., completed June 16, 2001 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 11, 2000, permitted to 3,500 ft.
It was permitted by Partee Drilling Inc. and has since transferred to Nordstrand Engineering Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Seven Rivers, San Andres, Clear Fork.
Its lease has reported 29.5K barrels of oil since December 1999, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
