The RRC has issued one drilling permit (amended 3 times), issued January 2, 2019, permitted to 12,000 ft.

It was permitted by Felix Energy Holdings II, LLC and has since transferred to Wpx Energy Permian LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Rustler, Delaware, Clear Fork, Glorieta.

Its lease has reported 835K barrels of oil and 1.67M mcf of gas since August 2019, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
