Shaffer M.C. 152 #4 (API 42-441-30737) is a plugged well in Taylor County, plugged June 25, 2008, last operated by E & R Oil.
The RRC has issued one drilling permit, issued December 23, 1983, permitted to 3,050 ft.
It was permitted by Reading & Bates Petroleum CO. and has since transferred to E & R Oil on the wellbore schedule.
Completion filings report 3 formation tops, including Flippen Sand, Capps Lime, Fry Sand.
Its lease has reported 5.4K barrels of oil and 1.69K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
