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

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.

Recent advances of modified polyacrylamide in drilling technology

Besides, PHPA can be applied in oilfield nowadays, especially in Daqing oilfield, where it is most superior with polymer flooding technique in China (Zhong et al., 2022). PHPA can develop long-chain molecules with their high molecular weight (Lam and Jefferis, 2014), which can overcome the contamination of bacteria and high mechanical force (Zhong et al., 2018).

The rheological studies show that GONs enhance the viscosity and viscoelastic properties of partially hydrolyzed polyacrylamide (PHPA) polymer. GONs form a robust three-dimensional network structure facilitated by hydrogen bonding with the PHPA polymer chain, which leads to the improvement of sweep efficiency.

Experimental evaluation of partially hydrolyzed polyacrylamide and silica nanoparticles solutions for enhanced oil recovery | Journal

The establishment of oil production well is becoming a challenge with the increasing demand for energy. The fulfillment of energy need requires large production of oil and gas as it is a primary source of energy. EOR is also important because of the enhancement in oil production from thirty percent to more than fifty percent. The chemical EOR is one of the techniques for the increment in oil

Mobility control and enhanced oil recovery using partially hydrolysed polyacrylamide (PHPA)

Polymers are often used as mobility controller for enhanced oil recovery. The present paper deals with the application of partially hydrolysed polyacrylamide (PHPA) polymer in enhanced oil recovery after the conventional water flooding. Experimental results show that viscosity of PHPA solution increases significantly on addition of small quantity of polymer, which in turn decreases the

FLODRILL For the Drilling Industry - SNF

PHPA is a water-soluble polymer. Interactions between the polymer molecules increase the viscosity of the drilling mud proportionally to the molecular weight of the product. PHPA can be used in fresh water, sea water or NaCl and KCl systems. PHPA is not compatible with high divalent contents in the water and high temperature applications.
