It was permitted by Cox, John L. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Its 2 leases have reported 126K barrels of oil and 484K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
