It was permitted by Welhausen Operating Company, LP and has since transferred to Gtg Operating LLC on the wellbore schedule.

Its lease has reported 134K barrels of oil and 187K mcf of gas since May 2005, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
