partially hydrolyzed polyacrylamide: enhanced oil recovery

Partially hydrolyzed polyacrylamide: enhanced oil recovery

Abstract 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.

Polyacrylamide-based Polymers for Enhanced Oil Recovery

The global average for oil recovery from existing oilfields is only between 20% and 40%, less than half the recovery rates typically achieved in gas fields. It has been estimated that improving oil recovery to match that of gas could more than double the time for which oil will be available.

Experimental evaluation of partially hydrolyzed

Chemical flooding using water-soluble polymers like partially hydrolyzed polyacrylamide (PHPA) has been industrially used as an EOR technique. The paper deals with the effect of nano-silica particles on viscosity as well as the shear rate of the polymer solution.

This minimum IFT was further reduced at optimum salinity and alkali. Finally, an increase of 14.3% oil recovery by surfactant flooding and 16.4% oil recovery by ASP slug injection containing NaOH alkali and partially hydrolyzed polyacrylamide (PHPA) polymer with 0.5 PV volume from carbonate plugs was achieved.

In addition, oil recovery tests were carried out in packed sand saturated with intermediate oil, where PHPA/Al 2 O 3, PHPA/SiO 2, and PHPA/TiO 2 systems produced additional recoveries of 15%, 10%, and 6%, respectively, in relation to the solution of PHPA. Thus, the use of nanoparticles can be considered promising to improve the polymer flooding
