Endicott #818H (API 42-461-39102) is a horizontal well in Upton County operated by Diamondback E&P LLC, completed February 13, 2014.
The RRC has issued one drilling permit (amended once), issued November 1, 2013, permitted to 12,000 ft.
It was permitted by Trp Operating LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its 2 leases have reported 485K barrels of oil and 824K mcf of gas since September 2007, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
