What is thermal stability of water soluble polyacrylamide (PAM) and partially hydrolyzed polymers?

Thermal stability of water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers under various solution conditions have been studied utilizing Quantum Mechanics Density Functional Theory (DFT) computational modeling method.

Which polymers are used in oilfield applications?

Water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers are among the most commonly used chemicals in oilfield applications.

What is the most widely used polymer for enhanced oil recovery?

In this respect, partially hydrolyzed polyacrylamide (HPAM) has become the most widely used polymer for enhanced oil recovery because of its low-price, good viscous properties, and well-known physicochemical characteristics.

What is polymer flooding?

Polymer flooding is one of the most effective tertiary oil recovery techniques. During this process, water soluble polymers are added to flooding water and then injected into reservoirs. Polymer flooding increases water viscosity and oil/water mobility ratio, and thereby enhances oil recovery.

Does polymer flooding improve oil recovery?

Polymer flooding increases water viscosity and oil/water mobility ratio, and thereby enhances oil recovery. Polymer flooding has been proven to be an effective means to enhance oil recovery for middle/high water-cut oilfields ( Gao, 2011 ).

How does HPAM affect the stability of oil droplets?

Zeta potential (mV) of the stimulated PWPF with addition of different MW, HD and concentration of HPAM. MW: average molecular weight; HD: hydrolysis degree. 3.5. Effect of HPAM on interfacial tension Interfacial tension of oil–water interface affects the stability of oil droplets.
