Schaefer #1 (API 42-133-36047) is a well in Eastland County operated by Katlaco Operating CO. Inc., completed October 12, 1984.
The RRC has issued 2 drilling permits between 1984 and 1986, permitted to 4,350 ft.
It was permitted by Katlaco Operating Company and has since transferred to Katlaco Operating CO. Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Arledge (Lake Sand), Mississipian, Mississippian, Ellenburger.
Its 2 leases have reported 7K barrels of oil and 11.4K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
