Abstract
A key parameter for application of polymers for waterflood mobility control is the loss of polymer due to<br>adsorption to the rock and more general retention during flow in porous medium. The paper discusses the<br>adsorption and retention properties of sulfonated co-polymers. These polymers have the same backbone<br>structure as partly hydrolysed polyacrylamide (HPAM), except for modified hydrophobic groups and that<br>the polymer is sulfonated to some extent. The group of polymers has been studied because of unusual salt<br>tolerance compared to other synthetic polymers. There is a need for polymers for high temperature and<br>high salinity reservoirs.
