Inhibition mechanism of cationic polyacrylamide on montmorillonite surface hydration: A molecular dynamics simulation study

Cationic polyacrylamide (CPAM), a typical drilling fluid shale inhibitor can prevent the clay swelling and maintain the wellbore stable. Understanding the adsorption behavior of CPAM on montmorillonite (MMT) surfaces is of great significance in explaining the excellent performance of cationic inhibitors.

Formation and Dissociation Kinetics of Methane Hydrate in Aqueous Oilfield Polymer Solutions (Polyacrylamide, Xanthan Gum, and ... - Semantic Scholar

Hydrate formation and deposition during drilling offshore oil and gas wells has been one of the major challenges faced by the oil and gas industry. The use of low-dosage hydrate inhibitor (LDHI), such as water-soluble polymers, has become an established technique to prevent hydrate plugging during drilling and transportation.

Synthetic polymers: A review of applications in drilling fluids

As a new generation of drilling-fluid formulations, in the last two decades synthetic-based drilling fluids (SBDF) has greatly enhanced the performance of oil-based drilling fluid's (OBDF). Specifically, in terms of environmental impacts, because SBDF is less toxic, achieves fast penetration rates, results in less fluid-related nonproductive time, and degrades faster than diesel and mineral

theoretical studies of hydrolysis and stability of polyacrylamide polymers

Theoretical studies of hydrolysis and stability of polyacrylamide polymers

The degree of hydrolysis ¦Ó of HPAM (Fig. 1 (c)) is defined as: ¦Ó = Y X + Y; 0 ¡Ü ¦Ó ¡Ü 1. Where X and Y are numbers of amide and carboxylic groups in polymer. Because our studies mainly focus on the hydrolysis reaction of the amide group, we model the PAM with a dangling ¨CCONH 2 group attaching to the middle carbon of the C 5.
