N. Wasson Unit #403 (API 42-501-35667) is a well in Yoakum County operated by Warren American Oil Company LLC, completed July 20, 2010 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued February 3, 2010, permitted to 5,600 ft.

It was permitted by Warren American Oil Company and has since transferred to Warren American Oil Company LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Rustler, Yates, San Andres.

Its lease has reported 1.19M barrels of oil and 576K mcf of gas since January 2010, last reporting in July 2026. The lease carries 38 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 44.9K barrels injected in the 12 months reported through September 2025.
