Duff A. H. Estate #7
Tom Green County · Dove Creek (Canyon -D-) field · Vertical
Duff A. H. Estate #7 (API 42-451-30610) is a well in Tom Green County operated by Trek Resources Inc., completed January 5, 1998.
The RRC has issued one drilling permit, issued April 8, 1980, permitted to 7,000 ft.
It was permitted by Champlin Petroleum CO. and has since transferred to Trek Resources Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Dean, Wolfcamp, Canyon.
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.
It holds an active disposal or injection permit, with 2.04K barrels injected in the 12 months reported through December 2025.
