Arnold 2 #103 (API 42-317-42188) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed August 22, 2023 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 1, 2019, permitted to 9,610 ft.

It was permitted by Lario Oil & Gas 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 lease has reported 891K barrels of oil and 733K mcf of gas since May 2019, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
