Walker Oil Unit C #1 (API 42-079-30433) is a plugged well in Cochran County, plugged May 18, 1994, last operated by F & M Oil & Gas Company.
The RRC has issued one drilling permit, issued May 26, 2009, permitted to 11,900 ft.
It was permitted by Blue Ridge Resources, LLC and has since transferred to F & M Oil & Gas Company on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Seven Rivers, San Andres.
Its 2 leases have reported 5.24K barrels of oil and 16 mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 39 barrels injected in the 12 months reported through January 2023.
