The RRC has issued 2 drilling permits between 1984 and 1990, permitted to 3,607 ft.

It was permitted by Shell Western E&P Inc. and has since transferred to Maverick Energy Group Inc. on the wellbore schedule.

Its lease has reported 2.04M barrels of oil and 474K mcf of gas since January 1993, last reporting in July 2026. The lease carries 470 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.
