Heirholzer 7 Gmk #21 (API 42-493-31892) is a plugged well in Wilson County, plugged October 30, 1991, last operated by Phoenix Operating Company Inc..

The RRC has issued 2 drilling permits between 1986 and 2000, permitted to 1,200 ft.

It was permitted by Double R Oil CO. and has since transferred to Phoenix Operating Company Inc. on the wellbore schedule.

Completion filings report one formation top, including Reklaw.

Its 2 leases have reported 1.57K barrels of oil since January 2000, last reporting in July 2026. The leases carry 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.
