Hardin County · Nona Mills (-I-) field  · Vertical

Nona Mills Field Unit #901 (API 42-199-00523) is a plugged well in Hardin County, plugged May 22, 2026, last operated by Mobil Producing TX. & N.M. Inc..

The RRC has issued 4 drilling permits between 1985 and 2000, permitted to 8,613 ft.

It was permitted by Smith Production Inc. and has since transferred to Mobil Producing TX. & N.M. Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Frio, Vicksburg, Yegua.

Its 2 leases have reported 98K barrels of oil and 236K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 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.
