Aspirating a fuel combustion engine with non-atmospheric gases to produce exhaust that can be efficiently used as EOR working fluid and/or recirculated in subsequent fuel combustion processes. The EOR working fluid is made up of a combination of gases created in a combustion process in a power-producing fuel combustion engine. This combustion process occurs using a mix of initial combustion ingredients that includes CO2 and relatively pure oxygen in the proportion required by the specific combustion device and the specific hydrocarbon fuel. The oxygen may be produced in lower value off peak periods and is stored until it is required. Where EOR or EGR working fluid has been injected into geologic formations and has then been re-circulated through the production process and provided to the engine combustion gas, there will typically be hydrocarbon components that the present invention makes use of to provide a portion or all of the fuel requirements for the engine power production system. |
