Plugged

Hockley County · Slaughter field · Vertical

Sundown NE. (San Andres) Unit #4 (API 42-219-32753) is a plugged well in Hockley County, plugged March 17, 2011, last operated by Aviator Energy LLC.

The RRC has issued one drilling permit, issued October 19, 1979, permitted to 5,000 ft.

It was permitted by Texland-Rector & Schumacher and has since transferred to Aviator Energy LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Anhydrite, Yates, San Andres, San Andrs.

Its lease has reported 311K barrels of oil and 106K mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 20 wells, so these are lease totals, not this well alone.
