Hertel B #4 (API 42-275-31725) is a well in Knox County operated by Richardson Bud II, completed November 15, 1985.

The RRC has issued one drilling permit, issued November 5, 1985, permitted to 2,250 ft.

It was permitted by Bristol Oil & Gas Corporation and has since transferred to Richardson Bud II on the wellbore schedule.

Completion filings report one formation top, including Tannehill.

Its 2 leases have reported 91K barrels of oil and 25 mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 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.
