Four Corners Sec 22 #2203U (API 42-461-39043) is a well in Upton County operated by Diamondback E&P LLC, completed May 21, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 13, 2013, permitted to 11,200 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Spraberry, Wolfcamp, Strawn, Atoka.
Its lease has reported 209K barrels of oil and 458K mcf of gas since March 2014, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
