Nix 31 #1 (API 42-115-32831) is a plugged well in Dawson County, plugged November 29, 2022, last operated by Diamondback E&P LLC.
The RRC has issued one drilling permit, issued August 17, 1994, permitted to 8,350 ft.
It was permitted by R K Petroleum Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 6 formation tops, including San Andres, T/Clearfork Lm, T/Spraberry, T/Gin.
Its lease has reported 179K barrels of oil and 136K mcf of gas since September 1994, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
