Blake W. R. #27
Cochran County · Slaughter field · Vertical
Blake W. R. #27 (API 42-079-33163) is a well in Cochran County operated by Novo Energy Resources, completed October 21, 2008.
The RRC has issued one drilling permit, issued August 22, 2008, permitted to 5,200 ft.
It was permitted by Walsh Petroleum, Inc. and has since transferred to Novo Energy Resources on the wellbore schedule.
Completion filings report one formation top, including San Andres.
Its 2 leases have reported 590K barrels of oil and 648K mcf of gas since January 1993, last reporting in July 2026. The leases carry 42 wells, so these are lease totals, not this well alone.
