Flo B #15WA (API 42-317-41352) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed January 28, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 27, 2018, permitted to 9,541 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 lease has reported 1.5M barrels of oil and 4.96M mcf of gas since January 2019, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
