    Effect of partially hydrolyzed polyacrylamide

    In this work, the effect of partially hydrolyzed polyacrylamide (HPAM) on the oil–water interfacial properties of produced water from polymer flooding (PWPF) was investigated. In addition, this study investigated the effects of three fiocculants (polyaluminium chloride PAC, cationic polymer FO4800SH, and nonionic polymer 402) on the stability

    Influences of partially hydrolyzed polyacrylamide (HPAM

    1. Introduction. Polymer flooding is an enhanced oil recovery (EOR) process. Water-soluble polymer, for example partially hydrolyzed polyacrylamide (HPAM), is added to the flooding water to improve the mobility ratio in the flooding process .Polymer flooding technology has been used in the later period of oil field producing.

    Theoretical studies of hydrolysis and stability

    Water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers are among the most commonly used chemicals in oilfield applications. In polymer-augmented water-flooding Enhanced Oil Recovery (EOR) processes, HPAM polymers are often used as mobility-control agents to increase the viscosity of stimulation fluids in

    Rheological Evaluation of HPAM fluids for EOR Applications

    Polyacrylamide is a synthetic water-soluble polymer. It usually consists of copolymers of various ratios of acrylic acid and acrylamide (CAENN & CHILLINGAR, 1996). The most widely used form of the HPAM for recovery methods is the partially hydrolyzed (LAKE, 1989; SORBIE 1991; SHENG, 2011). The HPAM is a polyelectrolyte with negative charges

    Interaction between sodium oleate and partially hydrolyzed

    The interaction between sodium oleate (C 17 H 33 COONa) and partially hydrolyzed polyacrylamide (HPAM) was investigated by rheological measurements. Mainly four series with concentration of HPAM to be 0.1 wt%, 0.2 wt%, 0.4 wt% and 0.6 wt%, respectively, were studied.
