Abstract:Cellulose nanocrystals (CNCs) have great application potential as environmentally friendly and multifunctional additives in drilling fluids. But their practical performance and utilization principles still need to further clarify. This paper investigated the effectiveness of two kinds of typical CNCs, including carboxylated cellulose nanocrystals (C-CNC) and sulfonated cellulose nanocrystals (S-CNC), on the rheological and filtration properties of water-based drilling fluids (WBDFs) under different concentrati… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
