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

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.

Optimization of Partially Hydrolyzed Polyacrylamide (HPAM) Utilized in Water-Based Mud While Drilling

Partially hydrolyzed polyacrylamide (HPAM) is a water-soluble polymer material used in oil fields [18,19]. It usually has a linear structure with high molecular weight [ 20 ] and is obtained by partial hydrolysis of PAM or by copolymerization of sodium acrylate with acrylamide [ 21 ].

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

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 ...

Supramolecular self-assembling hydrogel film based on a polymer blend of chitosan/partially hydrolyzed polyacrylamide for removing cationic dye

The supramolecular self-assembling hydrogel film was designed using a polymer blend of chitosan and partially hydrolyzed polyacrylamide (CS/PHPA), which was constructed with a controllable sol-gel transition, using a green one-pot external salt-assisted sol-gel transition and aqueous solution casting method that does not employ any toxic chemical crosslinking agents.

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 ...

Moreover, partially hydrolyzed polyacrylamide anionic (PHPA) could reduce the possibility of syneresis and improve the thermal stability of the Na-silicate gel []. Gelation time is considered the most complicated parameter, because it is affected by many factors such as temperature, activator concentration, salinity, and mechanical shear rate.
