Taylor County · Potosi (Cook Sand) field · Vertical
Thornton E. L. #1 (API 42-441-32086) is a plugged well in Taylor County, plugged June 27, 2014, last operated by Quantum Investments.
The RRC has issued one drilling permit, issued December 31, 1981, permitted to 2,000 ft.
It was permitted by Chalmers Operating CO., Inc. and has since transferred to Quantum Investments on the wellbore schedule.
Completion filings report one formation top, including Cook Sd.
Its lease has reported 2.18K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
