Polyelectrolyte polymers¡ªTypes, forms, and function

Abstract There is a wide range of polymeric polyelectrolytes available, both synthetic and naturally occurring. In this chapter we will focus our discussion on synthetic polymeric polyelectrolytes and we will cover the primary polyelectrolytes available on the industrial scale.

water-based polymer drilling fluid and method of use

Water-Based Polymer Drilling Fluid and Method of Use

A water-based drilling fluid comprises a polymer which is a non-ionic polymer or an anionic polymer. The polymer can be a polyacrylamide. The fluid is used for drilling subterranean formations containing heavy crude oil and bitumen-rich oil sands, and may comprise additional fluid components.

Polyacrylamide degradation and its implications in

The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21

Journal of Applied Polymer Science | Wiley Online Library

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

Rheology Properties of Underwater Cement Paste with Nonionic

In this article, underwater cement paste (UWP) was fabricated through using the high molecular nonionic polyacrylamide (PAM) as anti-washout admixtures (AWAs). The traditional coaxial rotary method was used to systematically investigate UWPs rheology parameters. A new B-HB model was successfully used for simulating the obtained shear stress versus shear rate diagram. The results showed that

Highlights Adsorption of high-molecular-weight polyacrylamide on glass was probed using AFM in 0.27 M LiCl, KCl, and KNO 3. Adsorbed amount of polymer on glass was in the following order: KCl > LiCl > KNO 3. The adsorption in LiCl and KCl was found to be rapid but with strong adhesion on retraction in KCl. Flat conformation and strong adhesion in KCl is attributed to binding effect of the

The Thermal Gelation Behavior and Performance Evaluation

The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by varying NPAM or PEI concentration, and a quadratic model is developed by statistical analysis, which

A delayed crosslinked polymer gel was developed for indepth water control in mature oilfields. The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by the variation of NPAM or PEI concentration, and a

Colloidal and Sedimentation Behavior of Kaolinite Suspension

The comprehension of kaolinite floc formation in the presence of a non-ionic polyacrylamide flocculant was improved by such a comprehensive visualization. The optimal polymers and operating conditions for the flocculation of clay minerals in tailing ponds may therefore be chosen using this knowledge.
