Edmondson #12 (API 42-335-33277) is a well in Mitchell County operated by Coalinga Corporation, completed January 2, 1987.
The RRC has issued one drilling permit, issued December 4, 1986, permitted to 1,850 ft.
It was permitted by Keck, W. M., JR., Mrs. and has since transferred to Coalinga Corporation on the wellbore schedule.
Completion filings report 5 formation tops, including Yates, Seven Rivers, Queen, Grayburg.
Its 2 leases have reported 428K barrels of oil and 41 mcf of gas since January 1993, last reporting in July 2026. The leases carry 40 wells, so these are lease totals, not this well alone.
