Sterling County · Parochial-Bade (Queen Sand) field · Vertical
Foster W. L. JR. -B- #21 (API 42-431-31846) is a well in Sterling County operated by D & D Well Service L.L.C., completed September 25, 1987.
The RRC has issued one drilling permit, issued May 19, 1987, permitted to 3,000 ft.
It was permitted by Union Oil Company Of California and has since transferred to D & D Well Service L.L.C. on the wellbore schedule.
Completion filings report 11 formation tops, including Queen, Clear Fork, Coleman Junction, Dean.
Its 2 leases have reported 163K barrels of oil and 6.15K mcf of gas since January 1993, last reporting in July 2026. The leases carry 24 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
