Dean C. S. A #2 (API 42-079-31147) is a plugged well in Cochran County, plugged April 23, 2008, last operated by Kala Oil Company.
The RRC has issued one drilling permit, issued November 12, 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.
Completion filings report one formation top, including Red Bed.
Its 2 leases have reported 24.7K barrels of oil and 34.2K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
