Benefits of technology

The patent describes a method of using steam to help recover oil from a formation. The steam is generated using fuel and oxygen in a high-pressure environment. The resulting flue gas is processed to remove water and compress the carbon dioxide. This allows the carbon dioxide to be sequestrated in another location. The technical effect is an improved method for oil recovery that reduces carbon dioxide emissions.

Problems solved by technology

Further, combustion at atmospheric pressure provides the flue gases at pressures too low for injection with the steam.

Embodiment Construction

[0012]Turning now to the detailed description of the preferred arrangement or arrangements of the present invention, it should be understood that the inventive features and concepts may be manifested in other arrangements and that the scope of the invention is not limited to the embodiments described or illustrated. The scope of the invention is intended only to be limited by the scope of the claims that follow.

[0013]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 m...

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a non-provisional application which claims benefit under 35 USC §119(e) to U.S. Provisional Application Ser. No. 61 / 837,686 filed Jun. 21, 2013 entitled “OXY-BOILER WITH STEAM ASSISTED PRODUCTION,” which is incorporated herein in its entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]None.FIELD OF THE INVENTION[0003]Embodiments of the invention relate to generating steam for steam assisted production of hydrocarbons with an oxy-boiler operated to facilitate flue gas applications.BACKGROUND OF THE INVENTION[0004]Recovery of heavy oil reserves often requires use of steam to heat and mobilize the oil through processes such as steam assisted gravity drainage (SAGD). Energy intensive steam generators produce the steam and resulting carbon dioxide emissions. Government regulations may make capture and sequestration of the carbon dioxide emissions necessary.[0005]Scrubbing flue gases of the steam generators with a...
