Wallville 321 #3H (API 42-357-33219) is a horizontal well in Ochiltree County operated by Highmark Energy Operating LLC, completed June 9, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 7, 2013, permitted to 7,573 ft.

It was permitted by Eog Resources, Inc. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Checkerboard Ls, Cleveland.

Its lease has reported 157K barrels of oil and 1.48M mcf of gas since January 2013, last reporting in July 2026. 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.
