  • Can hydrophobically associating polyacrylamide be used for enhanced oil recovery?
  • Overall, the use of hydrophobically associating EUR, HEC, and ASE for enhanced oil recovery is not well known. Currently, the domain on polymer research is focussed towards the application of HAPAM polymers for EOR operations. As a result, the remainder of this review would be focussed on hydrophobically associating polyacrylamide. Table 1.
  • Which polymers are used in oil fields?
  • 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.
  • Which polymers are used in EOR?
  • Synthetic polymers are man-made polymers with backbones that consist of relatively stable carbon-carbon bonds. Examples of synthetic polymers that are generally used in EOR are polyacrylamides and their derivatives, including hydrolysed polyacrylamide (HPAM), hydrophobically associating polyacrylamide (HAPAM), and copolymers of acrylamide .
  • Which oilfield has the largest polymer flooding in the world?
  • The largest polymer flooding in the world was implemented in the Daqing oilfield in 1996 , and by 2007, about 22.3% of the total production from the oilfield was attributed to polymer flooding . Generally, the injection process involves adding polymers into injected water to increase the water viscosity and improve oil recovery.
