Abstract
A material to be used for hydraulic fracturing, comprising argon maintained as a supercritical fluid, and a proppant. The material may also include any one of a variety of gels, foaming agents, and/or gases. The material may be used in a system to recover resources from bedrock, the system comprising the fracturing material, at least one mixer, a pump to inject the material into a bore well, and a recovery unit to recover the resource from the well. The material and system may be used in a variety of methods for extracting resources from bedrock, the method including mixing the proppant with the supercritical argon to form a mixture, pumping the mixture into a bore well, and recovering the resource from the bore well. Additionally, the material and bore well may comprise a structure used in the extraction of resources from bedrock.
