Abstract: Methods and systems relate to an oxy-boiler used to generate steam injected into a well for assisting recovery of hydrocarbons. Operating conditions of a burner for the oxy-boiler limits oxygen contamination in a resulting flue gas for carbon dioxide recovery and limits size of the oxy-boiler, which may thus be located proximate the well rather at a central processing facility. In contrast to a direct steam generation approach where resulting carbon dioxide is mixed with steam, the oxy-boiler also enables selection of a desired level of carbon dioxide injection, which may be provided with the flue gas that may be exhausted from the oxy-boiler at an injection pressure.

Abstract: Methods and systems generate steam and carbon dioxide mixtures suitable for injection to assist in recovering hydrocarbons from oil sands based on concentration of the carbon dioxide in the mixtures as influenced by temperature of water introduced into a direct steam generator. Increasing temperature of the water to above 200° C. before introduction into the direct steam generator may utilize heat from an electrical power generation unit. Enthalpy of this preheated water impacts amount of fuel needed to burn in the direct steam generator and hence the concentration of the carbon dioxide, which may be below 11% by mass percent of the steam.

Abstract: Systems and methods relate to recovering hydrocarbons by injecting into a reservoir steam along with carbon dioxide recovered from flue gases produced while generating the steam and from separation of produced fluids. Due to benefits from the carbon dioxide injection, carbon dioxide capture rates from the flue gases selected below fifty percent in such combined recovery of the carbon dioxide enables lower fuel consumption even given that additional fuel is needed for the carbon dioxide capture versus steam only operations. As the capture rates from the flue gases increase above fifty percent like when employed for sequestration purposes, such approaches use more fuel than the steam only operations and may not be cost efficient. A carbon dioxide recovery unit coupled to an air-fired boiler or an auxiliary oxy-fired boiler may supply the carbon dioxide recovered from the flue gases.

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.
