Abstract: A process for producing carbon dioxide for use in hydrocarbon recovery includes the steps of transporting a combustion turbine generator to an oilfield, operating the combustion turbine generator in combined cycle so as to produce steam, power and carbon dioxide, injecting the carbon dioxide into a reservoir located within the oilfield so as to produce hydrocarbons from the reservoir, and transmitting the power to a utility or for use by equipment at the oilfield. The combustion turbine generator has a size of no more than 175 megawatts. The combustion turbine generator operating in combined cycle has a heat rate of between 7,500 to 12,000 BTUs per hour. The carbon dioxide is compressed prior to be injected into the reservoir.
