West Spraberry Unit #217 (API 42-115-33040) is a well in Dawson County operated by JO Mill Oil Company LLC, completed November 12, 2022 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued March 20, 2000, permitted to 7,750 ft.

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

Completion filings report 5 formation tops, including Yates, San Andres, Clear Fork, Spraberry.

Its lease has reported 4.13M barrels of oil and 808K mcf of gas since December 1993, last reporting in July 2026. The lease carries 59 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
