Washington 5 #102 (API 42-317-43016) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed June 6, 2021 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued April 13, 2020, permitted to 10,605 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 358K barrels of oil and 639K mcf of gas since June 2021, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
