Polymer Injection for EOR: Influence of Mobility Ratio and Slug Size on Final Oil Recovery

Abstract: Among the many parameters needed to optimize a polymer flood is the choice of polymer viscosity, mobility ratio and polymer slug size that should be injected to maximize oil recovery. In this paper, a new polymer flooding experimental study is addressed to answer two questions. Firstly, considering a given crude oil, what optimal polymer solution viscosity should be injected? And secondly how much polymer solution should be injected during the polymer flood to maximise recovery? Experiments were… Show more

“…At the same injection time for ten years, the two types of polymers, the results produced were not much diff erent, synthetic polymers could produce 46.4% of OOIP, whilst biopolymers could produce oil 42.7% of total OOIP. According to (Juárez, et al, 2020) the sweep effi ciency can be related to the dispersion coeffi cient of the aqueous phase that is experimentally determined at the end of the water displacement when the oil is immobile.…”

“…This confi rms that a better sweep effi ciency was achieved when viscosity ratio was decreased and viscous fi ngering was minimized. Oil mobilization throughout the porous medium is easier when viscosity ratio is smaller by reducing the dispersion of the aqueous phase and insuring a sharper displacement front (Juárez, et al, 2020).…”
