Dean C. S. A #3 (API 42-079-31175) is a plugged well in Cochran County, plugged April 15, 2008, last operated by Kala Oil Company.
The RRC has issued one drilling permit, issued December 31, 1979, permitted to 5,100 ft.
It was permitted by Torreyana Oil Corp. and has since transferred to Kala Oil Company on the wellbore schedule.
Its lease has reported 24.7K barrels of oil and 34.2K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
