Abstract
Included are methods and systems for controlling the rheology of a treatment fluid. An example method comprises selecting a cellulose feedstock source to provide a cellulose capable of being processed into a nanocellulose having an average desired aspect ratio, and processing the cellulose with a cellulose processing technique to provide the nanocellulose with the average desired aspect ratio. The method further comprises adding the nanocellulose to the treatment fluid; wherein the nanocellulose alters a rheological property of the treatment fluid to provide an altered treatment fluid, and introducing the altered treatment fluid into a wellbore.
