Duff A. H. Estate #2
Tom Green County · Dove Creek (Canyon -D-) field · Vertical
Duff A. H. Estate #2 (API 42-451-30496) is a well in Tom Green County operated by Trek Resources Inc., completed September 1, 1979.
The RRC has issued one drilling permit, issued July 24, 1979, permitted to 7,000 ft.
It was permitted by Champlin Petroleum CO. and has since transferred to Trek Resources Inc. on the wellbore schedule.
Its 2 leases have reported 55.5K barrels of oil and 979K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
