Herrell E. Queen Sand Unit #110 (API 42-431-31812) is a well in Sterling County operated by Black River Operating LLC, completed February 2, 1987 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 15, 1986, permitted to 1,735 ft.
It was permitted by Marathon Oil Company and has since transferred to Black River Operating LLC on the wellbore schedule.

Its lease has reported 1.72M barrels of oil and 13K mcf of gas since January 1993, last reporting volume in March 2026. The lease carries 61 wells, so these are lease totals, not this well alone.
