Core Energy, LLC

What We Do 


Core Energy, LLC is headquartered in Traverse City, Michigan and was founded in 2003 by Robert G. Mannes (3rd generation in the Michigan Oil & Gas Industry). All of Core Energy's business activity is located in the State of Michigan. Current CO2 EOR operations are being conducted in Otsego County using CO2 captured from the gas plant removing CO2 produced from the Antrim Shale gas fields.

Miscible CO2 EOR operations are being conducted in depleted reservoirs (Silurian aged Niagaran pinnacle reefs) by injecting CO2 into the reservoir. This process increases the amount of crude oil that can be extracted from an oil field. In some instances the EOR recovery has exceeded 50% of volumes produced during the primary production phase.

Core Energy currently operates 10 EOR projects that are in various phases of development.  By the end of 2016, these projects have already produced in excess of 2 million barrels of oil that would not have otherwise been produced wile sequestering over 2 million tonnes of CO2 in the process.


Core Energy, LLC is actively involved in innovative oil production technologies and is the only company in Michigan currently performing CO2 Enhanced Oil Recovery (EOR) operations, which is making Michigan's economy stronger and more energy independent while sequestering CO2
