Schroeder T. S. #4L (API 42-355-06587) is a well in Nueces County operated by Pennzoil Exploration & Prod. CO., completed December 30, 1967.
The RRC has issued 2 drilling permits between 1993 and 2002, permitted to 5,790 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Pennzoil Exploration & Prod. CO. on the wellbore schedule.
Completion filings report 7 formation tops, including Comstock, 5100, 5100', 5450.
Its 3 leases have reported 1.8K barrels of oil and 1.26M mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
