Abstract: Systems and methods relate to recovering hydrocarbons by injecting into a reservoir outputs from two different types of steam generators along with carbon dioxide. Synergistic results enable lower fuel consumption for such a hybrid based approach versus either type of steam generator alone. One steam generator vaporizes water by thermal transfer from combustion with exhaust from the combustion remaining separated from the steam. Since this type of steam generator outputs a limited carbon dioxide concentration with the steam, at least part of the carbon dioxide injected comes from recycling the carbon dioxide separated out of production fluids recovered from the reservoir. Another steam generator produces the steam by direct water contact with combustion products to produce a resulting fluid including the steam and additional carbon dioxide.
