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

Molecular Structure Design Principles for Clay Hydration Inhibitors | Chemistry and Technology of Fuels and Oils - Home

The crucial challenge associated with water-based drilling fluids for the extraction of shale gas is the inhibition of clay hydration in the drilling operation. The inhibition efficiency of shale inhibitors is determined by the content of particular groups in the molecule. In this report we studied the inhibition performance, inhibition mechanism, and environmental friendliness of three

Optimization of Partially Hydrolyzed Polyacrylamide (HPAM) Utilized in Water-Based Mud While Drilling

Water-soluble polymers are becoming increasingly important in various applications, such as stabilizer fluids and drilling muds. These materials are used as viscosifiers and filtration control agents, flocculants, and deflocculants due to their superior properties in increasing viscosity and gelling ability in the presence of crosslinkers. In general, studying the rheological behavior of

Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization. The effects of the monomer concentration, initiator concentration, reaction time, feeding temperature and reaction temperature on the molecular weight were systematically investigated through single-factor and orthogonal experiments.
