The RRC has issued one drilling permit (amended twice), issued February 20, 2020, permitted to 17,500 ft.
It was permitted by Element Petroleum OP Iii, LLC and has since transferred to High Noon Resources LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Santa Rosa, Yates, Queen, Grayburg.
Its lease has reported 552K barrels of oil and 498K mcf of gas since September 2021, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
