Herrell E. Queen Sand Unit #WS1 (API 42-431-31794) is a well in Sterling County operated by Black River Operating LLC, completed April 5, 2019 and listed as water supply on the RRC schedule.
The RRC has issued one drilling permit, issued February 14, 1986, permitted to 2,400 ft.
It was permitted by Marathon Oil Company and has since transferred to Black River Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Grayburg, Seven Rivers, Queen, Queenburg.
Its lease has reported 1.72M barrels of oil and 13K mcf of gas since January 1993, last reporting in July 2026. The lease carries 61 wells, so these are lease totals, not this well alone.
