Wth 21-16 A #112 (API 42-329-43119) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed November 3, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 6, 2019, permitted to 8,374 ft.

It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 1.45M barrels of oil and 4M mcf of gas since May 2019, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
