Recent advances of modified polyacrylamide in drilling technology

Previous studies have shown the effectiveness of rheology modifier in drilling fluid. For instance, Balding et al. (2020) studied the water-based drilling fluid formulation with various formulations via free radical grafting and physical blending with chemical additives, such as polystyrene sulfonate (PSS), polyacrylamide (PAM), cellulose nanocrystal (CNC), and modified CNC with vinyl

Synthesis of novel modified acrylamide copolymers for montmorillonite flocculants in water-based drilling fluid | BMC Chemistry | Full Text

The significance of clays in drilling muds lies in their capacity to achieve optimal viscosity levels with relatively low solid concentrations and to sustain the desired viscosity throughout the entire drilling operation. In the oil drilling industry one of the important minerals is montmorillonite.
