Dawson County · Spraberry W. (Deep Spraberry) field · Shut In · Vertical
West Spraberry Unit #13 (API 42-115-00739) is a well in Dawson County operated by JO Mill Oil Company LLC, completed April 13, 2011 and listed as shut in on the RRC schedule, shut in November 1, 2019.
The RRC has issued one drilling permit, issued March 7, 1985, permitted to 7,625 ft.
It was permitted by Texaco Inc. and has since transferred to JO Mill Oil Company LLC on the wellbore schedule.
Completion filings report one formation top, including Spraberry.
Its 2 leases have reported 4.13M barrels of oil and 816K mcf of gas since January 1993, last reporting in July 2026. The leases carry 70 wells, so these are lease totals, not this well alone.
