Benefits of technology

[0007] It is thus one aspect of the present invention to provide a cost effective, economical apparatus and method to exploit and produce combustible products from hydrocarbon reservoirs and generate electrical energy in remote and isolated locations. Thus, in one embodiment of the present invention, produced natural gas from a subterranean formation is utilized to power an electrical generator which produces electrical energy for transmission through local power lines and grid systems.
[0008] It is a further aspect of the present invention to provide a method and apparatus for generating substantially pollution free energy from hydrocarbon reservoirs which contain oil and natural gas. Thus, in one embodiment of the present invention the exhaust byproducts from an engine used to drive an electrical generator is contained, scrubbed to remove water and other impurities, and reinjected into a subterranean formation to eliminate emissions of toxic and carbon containing exhaust gases to the atmosphere.
[0009] It is a further aspect of the present invention to provide an apparatus and method for improving in a cost effective manner the productivity of an existing hydrocarbon reservoir, which at the same time substantially eliminating toxic gases and exhaust byproducts from entering the atmosphere. Thus, in one aspect of the present invention the exhaust gases created during electrical generation are collected, compressed and reinjected into the producing hydrocarbon reservoir. The injection of the exhaust gases thus increases the reservoir pressure and enhances the production rate and ultimate recovery from the hydrocarbon reservoir.

Problems solved by technology

Although extremely beneficial as a fuel source, these hydrocarbon energy sources emit toxic fumes and carbon containing compounds in their exhaust when burned, and are thus believed to be a major contributor to global warming, air pollution and other undesirable conditions known to cause harm to human health and the environment.
Although recent improvements to power generating exhaust systems including catalytic converters, exhaust scrubbers and other similar products have improved the efficiency and reduced emissions of power plants which rely on hydrocarbon fuel sources, there is still a significant problem with regard to how these toxic emissions from hydrocarbon fuels can be significantly reduced or eliminated.
In conjunction with the aforementioned problem of toxic and carbon containing gas emissions, an additional problem exists in producing and transporting hydrocarbon fuels from remote locations to existing electrical power plants located near high population densities.
Since the discovered reserves are not sufficient to justify the economic expense of a gas transmission pipeline, many of these smaller hydrocarbon reservoirs are never exploited, thus preventing the production of valuable energy resources from remote locations.

Embodiment Construction

[0025] Referring now to the drawings, FIG. 1 depicts a flow schematic of one embodiment of the present invention and which identifies the flow path of a hydrocarbon fluid and the creation of electrical energy associated therewith. More specifically, the flow schematic depicts a producing geologic formation 2 which generally comprises a porous and permeable subterranean formation which is capable of storing, a hydrocarbon fluid such as oil, natural gas, condensate, or other combustible hydrocarbons (hereinafter “hydrocarbon fluid”). The natural gas may be comprised of methane, ethane, butane, propane, as well as liquid condensate associated therein. As well known in the oil and gas industry, these hydrocarbon fluids may be produced through a producing wellbore 6 either naturally due to a high bottom hole pressure in the producing geologic formation, or by means of artificial lift using pumps, down-hole motors, sucker-rods, and other available means well known in the art to extract th...

Abstract

The present invention relates to the generation of substantially pollution free energy by utilizing hydrocarbons to create electrical energy, while reinjecting exhaust fumes or other byproducts into a subterranean formation. The present invention further relates to managing and supplying this electrical energy to at least one of a variety of subprocesses for producing a fuel product, such as hydrogen or ethanol. Alternatively, electrical power can be generated from a non-hydrocarbon source such as thermal, solar, wind or other power source to produce electrical energy, which in turn may be used to produce fuel products or other forms of usable energy. Thus, remote, low reserve oil and gas fields may be exploited and produced without requiring the construction of expensive gas transmission lines.
