On-Site Generation of a Fracturing Fluid Stream and Systems and Methods Utilizing the Same

摘要

On-site generation of a fracturing fluid stream system includes a fracturing fluid generation assembly and a fracturing fluid supply assembly. The fracturing fluid generation assembly is configured to receive a hydrocarbon stream and to generate a fracturing fluid stream from the hydrocarbon stream. The fracturing fluid stream has an oxygen concentration, which is less than a limiting oxygen concentration for supporting combustion of a combustible fluid that is present within a subterranean formation. The fracturing fluid stream also has a combustible portion, which defines a concentration that is below a lower flammability limit of the combustible portion in the fracturing fluid stream. The fracturing fluid supply assembly is configured to receive the fracturing fluid stream and to convey the fracturing fluid stream to the subterranean formation to fracture the subterranean formation.

1. A system for fracturing a region of a subterranean formation that includes a combustible fluid, the system comprising:
a fracturing fluid generation assembly that is configured to receive a hydrocarbon stream and to generate a fracturing fluid stream therefrom at a supply pressure, wherein the fracturing fluid stream has an oxygen concentration and a combustible portion, wherein a concentration of the combustible portion in the fracturing fluid stream is below a lower flammability limit of the combustible portion in the fracturing fluid stream, further wherein the oxygen concentration in the fracturing fluid stream is less than a limiting oxygen concentration for supporting combustion of the combustible fluid; and a fracturing fluid supply assembly that is configured to receive the fracturing fluid stream from the fracturing fluid generation assembly and to convey the fracturing fluid stream to the region of a subterranean formation via a wellbore that extends therein at a fracturing pressure that is sufficient to fracture the region.
