“…High molecular weight of HPAM also makes it less suitable for oil reservoirs with low permeability. 82 It was found that the viscosity of some high molecular weight polymers was low when compared to the viscosity of low molecular weight polymers after shearing. 83 Only few studies have been conducted on the effect of pressure on HPAM viscosity.…”

“…46 But there is always an optimum concentration of the hydrophobic monomer and further increase reduces the viscosity. 82 In HMA terpolymer containing AM, AMPS, and 2-vinylnephthalene (VN), the solution viscosity increased when the hydrophobic monomer VN content was increased up to 0.75%. However, at a 1% hydrophobic content the viscosity reached a minimum.…”

Polymer flooding is one of the most promising techniques for the recovery of remaining oil from light oil reservoirs. Water soluble polymers are used to enhance the viscosity of displacing fluid and to improve the sweep efficiency. In this paper, water soluble polymers used for chemical enhanced oil recovery are reviewed. Conventional and novel modified polymers are discussed along with their limitations. The review covers thermal stability, rheology, and adsorption behavior of various polymer systems in sandstone and carbonate reservoirs. Field and laboratory core flooding data of several polymers are covered. The review describes the polymer systems that are successfully applied in low-temperature and low-salinity reservoirs. Comprehensive review of current research activities aiming at extending polymer flooding to high-temperature and high-salinity reservoirs is performed. The review has identified current and future challenges of polymer flooding.

“…Chemical enhanced oil recovery (cEOR) is one of the techniques employed to oil reservoirs to recover the remaining oil which cannot be recovered by primary recovery. A number of chemical flooding methods were reported in the literature, such as surfactant [2][3][4][5], polymer [6][7][8], alkali [9], surfactant/polymer [10][11][12][13] and alkali/surfactant/polymer [14,15]. Chemical methods are utilized to increase the viscosity of displacing fluid for better mobility control, to increase the sweep efficiency and to reduce the interfacial tension (IFT) between water and crude oil.…”

Abstract. Cationic, hydrophobically associating polyacrylamide (PDA) was synthesized via the inverse miniemulsion polymerization in the presence of template. Dimethyloctane(2-acrylamidopropyl)ammoniumbromide (DOAB) was synthesized via quaternization reaction and used as the hydrophobic monomer. Polyacrylic acid (PAA) was used as template for the oppositely charged DOAB. The distribution of DOAB in the inverse miniemulsion and the solution viscosity behaviors of PDA were investigated. The results showed that the complexes of DOAB and PAA were located not only at the interface of the inverse miniemulsion droplets and oil phase but also in the interior of inverse miniemulsion droplets. PDA prepared with template exhibited remarkable enhancement of solution viscosity (thickening ability). And the optimal thickening ability was obtained when the aqueous phase pH was 6.5 and the ratio of DOAB to PAA was 1. The thickening ability of PDA was improved with increasing DOAB content. PDA prepared with template showed stronger association ability than that prepared without template for its longer hydrophobic block structure, which was further supported by the plots of fluorescence spectra.
