A Synergy between Controlled Salinity Brine and Biosurfactant Flooding for Improved Oil Recovery: An Experimental Investigation Based on Zeta Potential and Interfacial Tension Measurements

<p>Rate of spontaneous imbibition of FMB (blue circle), CSB (dark red square), CSBSB-G (green rhombus), and CSBSB-R (golden triangle). Plot (a) shows rate of imbibition using single brine solution while (b) shows rate of imbibition with change in brine solutions.</p>
