West Sundown Unit #229H (API 42-219-37464) is a horizontal well in Hockley County operated by Oxy USA Eor LLC, completed April 27, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued November 5, 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.
