WebJan 7, 2024 · The high layered vertical heterogeneity in permeability and unfavorable oil-water viscosity ratio in reservoir conditions (>20) of the field predetermined the need for chemical methods to enhanced oil recovery (EOR), such as polymer flooding. Polymer flooding pilot has been conducted since 2014. The analysis is based on current and … WebOct 9, 2024 · The presence of the polymer increases the viscosity of the injected water, which reduces the difference in the speeds at which the water and oil travel and minimizes the tendency of water to finger through oil 3. This in turn results in more oil being pushed towards the production well and significantly improves oil recovery.
WebDec 1, 2014 · The two sets that are extensively used for enhancing oil recovery include synthetic polymers and biopolymers [63]. The most utilized polymers today are the synthetic and partially HPAM (hydrolyzed polyacrylamide), the modified natural polymers and the biological polysaccharide, Xanthan [64], [65].
