Experimental Study of Enhancing Oil Recovery with Weak Base Alkaline/Surfactant/Polymer

<div>(a) Relationship between incremental oil recovery and IFT when Na<sub>2</sub>CO<sub>3</sub> concentration varies. (b) Relationship between incremental oil recovery and viscosity when Na<sub>2</sub>CO<sub>3</sub> concentration varies. The surfactant concentration is 0.3 wt% and polymer concentration is 2000 mg/L.</div>
