Polymer flooding is one of the most promising techniques for the recovery of remaining oil
from light oil reservoirs. Water soluble polymers are used to enhance the viscosity of …

It is well-known that surfactants are molecules able to modify the surface properties of the
liquid in which they are introduced (usually water). The simultaneous presence of both …

Recent developments in the field of water-soluble polymers aimed at enhancing the
aqueous solution viscosity are reviewed. Classic and novel associating water-soluble …

The aging of the existing reservoirs makes the hydrocarbon extraction shift toward newer
reserves, and harsh conditioned carbonates, which possess high temperature and high …

Heavy crude oil is one of the most precious and complex molecular mixtures available, with
considerable economic relevance. Nevertheless, its high viscosity and complicated …

Water-soluble polymers are known to be used in chemically enhanced oil recovery (EOR)
processes, but their applications are limited in high-temperature and high-salinity oil …

The influence of salt and temperature on the viscosity of a hydrophobically modified
polyacrylamide-based (PAM-based) novel functional polymer (RH-4) was investigated. To …

High-molecular-weight polyacrylamide (PAM) has been widely used in chemically
enhanced oil recovery (EOR) processes under mild conditions, but its poor tolerance to high …

Dilute and semi-dilute solution properties of polyacrylamide (PAM) and its hydrophobically
modified analogues (HAPAMs) in both pure water and brine were compared by means of …

The synthetic water-soluble polymer, partially hydrolyzed polyacrylamide (HPAM), has been
most widely used for enhanced oil recovery (EOR); however, its poor thermal stability and …
