Another reason is its degradation in harsh reservoir conditions. A third reason is economics and the high initial investments for facilities. Combination flooding...

Extending polymer flooding to carbonate reservoirs has been challenging because of adsorption loss and polymer availability for high-temperature, high-salinity (HT/HS) reservoirs. In this study, the authors establish that HT/HS polymers can exhibit low adsorption and retention...
