Partially hydrolyzed polyacrylamide: enhanced oil recovery applications, oil-field produced water pollution, and possible solutions

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.

Electrochemical degradation of hydrolyzed polyacrylamide by a novel La-In co-doped PbO2 electrode: Electrode characterization

Hydrolyzed polyacrylamide (HPAM) has been widely used in polymer flooding to improve oil recovery because of its good water solubility, easy synthesis, and low cost [61], [62]. However, it brought a large amount of HPAM sewage with high viscosity and serious emulsification at the same time.

Viscosity of partially hydrolyzed polyacrylamide under shearing and heat - Journal of Petroleum Exploration and Production Technology

For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery. In reality, however, polymers can be severely degraded by shearing and heat in the underground environment. This phenomenon is studied in this paper.

Molecular dynamics simulation of adsorption and diffusion of partially hydrolyzed polyacrylamide on kaolinite surface

Partially hydrolyzed polyacrylamide (HPAM) is widely used in actual tertiary oil recovery, and the degree of hydrolysis is generally between 25 % and 35 % [6]. Whether it is PAM or HPAM, these polymer molecular chains have the characteristics of flexibility, easy molecular conformation change, and extremely flexible entanglement, so they have high viscosity and good rheological adjustment ability.
