Exxon-Cowden #2TM (API 42-461-35172) is a well in Upton County operated by Apache Corporation, completed March 16, 2007 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 31, 2006, permitted to 9,015 ft.
It was permitted by Mariner Energy, Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Its lease has reported 83.7K barrels of oil and 292K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
