Biomass slurry preparation for subterranean injection

Abstract

A method for preparing a biomass slurry for subterranean injection can include obtaining a quantity of a biomass slurry feedstock from a source, wherein the biomass slurry feedstock comprises a plurality of pieces, where the biomass slurry feedstock comprises a composite of cellulose in a lignin matrix, hemicellulose fibers in a lignin matrix, or any combination thereof, and where each of the plurality of pieces has a size not to exceed approximately 60,000 μm. The method can also include obtaining a volume of a fluid, where the fluid comprises a salt content of at least approximately 0.05%. The method can further include mixing the plurality of pieces and the volume of fluid to form the biomass slurry, where the plurality of pieces are substantially evenly distributed within the fluid, and where the biomass slurry is configured to be used in the subterranean injection.
