In recent years, global warming has been blamed on the so called ＇＇greenhouse effect＇＇ and has caught the attention of scientists and politicians throughout the world. There is an increasing concern surrounding the emission levels of greenhouse gases, particularly carbon dioxide (CO2). This paper is an extension of earlier work((1)) to show how cogeneration concepts can be used to reduce production costs by simultaneously producing electricity, CO2 and steam for enhanced oil recovery (EOR) applications.
