Liberty Belle 23-18 Unit 1 #221 (API 42-317-41761) is a horizontal well in Martin County operated by Diamondback E&P LLC, completed August 10, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 18, 2018, permitted to 12,000 ft.

It was permitted by Endeavor Energy Resources L.P. 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 1.47M barrels of oil and 5.3M mcf of gas since August 2019, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
