Calla Mae #2 (API 42-081-30730) is a plugged well in Coke County, plugged November 20, 2008, last operated by Quail Ridge Petroleum LLC.
The RRC has issued one drilling permit, issued January 24, 1979, permitted to 6,800 ft.
It was permitted by Rankin Oil CO. and has since transferred to Quail Ridge Petroleum LLC on the wellbore schedule.
Its 3 leases have reported 89.2K barrels of oil and 806K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
