West Spraberry Unit #301 (API 42-115-00708) is a well in Dawson County operated by JO Mill Oil Company LLC, completed September 21, 1994 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 15, 1997, permitted to 6,893 ft.

It was permitted by Texaco E & P Inc. and has since transferred to JO Mill Oil Company LLC on the wellbore schedule.

Its 2 leases have reported 4.13M barrels of oil and 813K mcf of gas since January 1993, last reporting in July 2026. The leases carry 62 wells, so these are lease totals, not this well alone.
