Abstract
Various processes are disclosed for producing nanocellulose materials following steam extraction or hot-water digestion of biomass. Processes are also disclosed for producing nanocellulose materials from a wide variety of starting pulps or pretreated biomass feedstocks. The nanocellulose materials may be used as rheology modifiers in many applications. Water-based and oil-based drilling fluid formulations and additives are provided. Also, water-based and oil-based hydraulic fracturing fluid formulations and additives are provided. In other embodiments, polymer-nanocellulose composites are provided.
