The RRC has issued one drilling permit, issued June 18, 2021, permitted to 9,500 ft.
It was permitted by Petrolegacy Energy II, LLC and has since transferred to Ovintiv USA Inc. on the wellbore schedule.
Completion filings report 11 formation tops, including Santa Rosa, Yates, Queen, Grayburg.
Its lease has reported 733K barrels of oil and 545K mcf of gas since August 2021, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
