The RRC has issued one drilling permit, issued July 11, 1984, permitted to 9,400 ft.

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

Its lease has reported 101K barrels of oil and 431K mcf of gas since January 1993, last reporting in April 2020. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
