Sterling County · Herrell field · Producing · Vertical
Txl -A- #15 (API 42-431-31248) is a well in Sterling County operated by Black River Operating LLC, completed December 4, 1982 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 9, 1982, permitted to 2,700 ft.
It was permitted by Enoc Petroleum Company and has since transferred to Black River Operating LLC on the wellbore schedule.
Its lease has reported 111K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
