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

Hydrodynamic Analysis and Cake Erosion Properties of a Modified Water

Drilling mud has various roles, such as cooling the drill bit and drill string, hole cleaning or transporting the drilling cuttings to the surface, stabilizing the wellbore, and proper filtration. (1?5) Various drilling fluid types are used, including water-based and oil-based drilling muds (WBDMs and OBDMs).

Fabricating an anionic polyacrylamide (APAM) with an anionic block

On one hand, the particles with opposite charge can be thoroughly neutralized and destablized by the anionic chemical group. 11,12 On the other hand, these destabilized particles will be captured by the molecule chain of APAM to agglomerate and form large and compact flocs, and thus flocculation occurs. 13 During the solid-water separation process, the main mechanisms involved are charge

Deep and ultra-deep well exploration is rapidly becoming an important means to meet the enormous world oil and gas demands. Currently, many rheology builders exhibit poor salt tolerance and display low thermal stability at elevated temperatures, rendering them inefficient for deep-drilling operations. In this study, synthesis of a suitable polymer-based rheology enhancer with excellent thermal
