Polymer flooding
WebDec 1, 2024 · Water soluble polymer such as Hydrolyzed Polyacrylamide (HPAM) are used as mobility control agent in chemical EOR applications such as polymer, alkali/polymer and alkali/surfactant/polymer flooding. They are dissolved in the injection water so as to decrease the mobility ratio between the pushing fluid and the oil to be displaced ( Sorbie, … WebIn the past, polymer flooding was mainly the subject of research. The results of this research are spread over a vast number of single publications, making it difficult for someone who has not kept up-to-date with developments during the last 10 to 15 years to judge the suitability of polymer flooding to a particular field case.
