Size reduction to micron to nano-size range is rapidly developing technology applied to foods in the recent decades. Indeed, the high presence of fiber in bran and the co-presence of lipids and lipase in germ are often considered as downsides for the possibility of application of this by-product. However our last studies and research in related fields of the BIOCHEMICAL modification of Lignocellulolytic wastes and by-products has led to brilliant application of these valuable compounds into new area chemical and petrochemical applications. however; Several processing methods have been developed to modify the functional, textural and chemical properties of wheat bran, which can affect its function in Water-based fluids treated media. Of those important works that has resulted using its the mechanical properties and structure are in bran-enriched expanded extrudates and its improved water and fat absorption capacity through hydrothermal properties and a fine milling process. However; current work and study offers new approaches in related of alternating usage of these valuable product in related to oil field and drilling mud rheology modification procedure through hydrothermal stabilization and fine grinding modification of wheat bran texture for maximum incorporation of fibers in drilling mud formulations which can be used in pills, sweeps and maintenance treatments with minimal adverse effect on rheology and filtration control properties. The cellulosic material that is modified using these processes, helps decrease the permeability of the wall cake in all drilling fluid types applying the formulation containing.
