University 7-31B #D 1
Martin County · Spraberry (Trend Area) field · Directional
University 7-31b #D 1 (API 42-317-41454) is a well in Martin County operated by Diamondback E&P LLC, completed June 22, 2021.
The RRC has issued one drilling permit, issued May 17, 2018, permitted to 14,090 ft.
It was permitted by Qep Energy Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.
Its 2 leases have reported 165K barrels of oil and 654K mcf of gas since January 2009, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 5.14M barrels injected in the 12 months reported through January 2026; TexNet located 20 M2+ earthquakes within 10 km over the last two years.
