Gunter #20D (API 42-383-40890) is a well in Reagan County operated by Diamondback E&P LLC, completed September 22, 2020.
The RRC has issued one drilling permit, issued June 25, 2020, permitted to 7,850 ft.
It was permitted by Hibernia Resources Iii, LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Rustler, Yates, Queen.
Its 2 leases have reported 72.5K barrels of oil and 385K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 5.83M barrels injected in the 12 months reported through November 2025; TexNet located 0 M2+ earthquakes within 10 km over the last two years.
