Nanoparticles-Based Deflocculant: A Sustainable Alternative to Lignite Based Additive of Drilling Fluids
Deflocculants play a critical role in controlling rheology, gel strength, and solids dispersion in water-based drilling fluids, particularly under high-solids build up and elevated temperature conditions. Conventional deflocculants such as lignosulfonates and lignite-based additives remain widely used; however, they...
