Schaefer #4 (API 42-133-32826) is a plugged well in Eastland County, plugged September 19, 2025, last operated by Interstate Explorations LLC.

The RRC has issued one drilling permit, issued February 20, 1981, permitted to 1,500 ft.

It was permitted by Ridgeway Oil Expl & Dev., Inc and has since transferred to Interstate Explorations LLC on the wellbore schedule.

Completion filings report one formation top, including Patio.

Its lease has reported 48.9K barrels of oil and 40 mcf of gas since January 1993, last reporting in July 2026. The lease carries 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.
