It was permitted by Laredo Petroleum, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its lease has reported 222K barrels of oil and 1.44M mcf of gas since July 2009, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
