polyacrylamide degradation and its implications

Polyacrylamide degradation and its implications

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,...

dynamic interfacial tensions of surfactant and polymer

Dynamic Interfacial Tensions of Surfactant and Polymer

Ma et al. studied the effect of partially hydrolyzed polyacrylamide (HPAM) on the IFT between anionic and negative non-ionic surfactants and found that the polymer and surfactant interact to form a mixed adsorption film . The concentration of HPAM will affect the tightness of the interfacial membrane structure and the IFT.

partially hydrolyzed polyacrylamide: enhanced oil recovery

Partially hydrolyzed polyacrylamide: enhanced oil recovery

Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery.

interaction between sodium oleate and partially hydrolyzed

Interaction between sodium oleate and partially hydrolyzed

Among various anionic polyelectrolytes, partially hydrolyzed polyacrylamide (HPAM) is the most prevalent one due to its important role in many fields, especially in the chemical flooding progress in oilfield [13], [14]. Practice has shown that the rheological property and interfacial tension of injected fluid have an important effect on oil

determination of surfactant concentration in surfactant

Determination of Surfactant Concentration in Surfactant

Three different types of surfactants (anionic SA, cationic SC and non-ionic SN) were and a partially hydrolyzed polyacrylamide (HPAM) were chosen to be mixed as SA-HPAM, SC-HPAM and SN-HPAM. For the elimination of the polymer interferences, a pre-treatment of the mixtures using 1% NaClO at high temperature for certain hours was conducted.

Rheological Properties of Partially Hydrolyzed Polyacrylamide

This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aqueous HPAM-based SiO2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times. The results show that the inclusion
