The RRC has issued one drilling permit, issued December 19, 2017, permitted to 12,000 ft.
It was permitted by Exl Petroleum Operating Inc. and has since transferred to Ovintiv USA Inc. on the wellbore schedule.

Its lease has reported 506K barrels of oil and 519K mcf of gas since August 2017, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
