West Sundown Unit #226 (API 42-219-37461) is a well in Hockley County operated by Oxy USA Eor LLC, completed January 1, 2024 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued October 4, 2018, permitted to 5,700 ft.

It was permitted by Oxy USA Inc. and has since transferred to Oxy USA Eor LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, San Andres, Abo.

Its lease has reported 6.39M barrels of oil and 4.65M mcf of gas since May 2016, last reporting in July 2026. The lease carries 240 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 19K barrels injected in the 12 months reported through December 2025; TexNet located 0 M2+ earthquakes within 10 km over the last two years.
