Ector County · Goldsmith N. (San Andres Con.) field · Producing · Vertical
Cowden J. F. #11 (API 42-135-02663) is a well in Ector County operated by Diamond S Energy Company, completed June 24, 1979 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 21, 1979, permitted to 8,600 ft.
It was permitted by Texaco Inc. and has since transferred to Diamond S Energy Company on the wellbore schedule.
Its 2 leases have reported 4.36M barrels of oil and 6.84M mcf of gas since January 1993, last reporting in July 2026. The leases carry 55 wells, so these are lease totals, not this well alone.
