Eastland County · Adams (Duffer Lower) field · Producing · Vertical
Duffer A #2 (API 42-133-35594) is a well in Eastland County operated by Byrne Oil Company, completed March 17, 1984 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 29, 1983, permitted to 3,560 ft.
It was permitted by Byrne, Robert E. and has since transferred to Byrne Oil Company on the wellbore schedule.
Completion filings report one formation top, including Duffer.
Its lease has reported 116K barrels of oil and 218K mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
Operator of record
