Chromatographic lag in polymer flooding
Input(s)
A: Adsorption Rate (g polymer/g rock)
\(\rho\): Rock Density \((\mathrm{g} / \mathrm{cc})\)
\(\emptyset\): Porosity (fraction)
C: Polymer Concentration \((\mathrm{g} / \mathrm{cc})\)
\(S_{w}\): Water Saturation (fraction)
Output(s)
CL: Chromatographic Lag (dimensionless)
Formula(s)
\[
\mathrm{CL}=\frac{1}{1+\frac{\mathrm{A} * \rho *(1-\emptyset)}{\mathrm{C} * \emptyset * \mathrm{~S}_{\mathrm{w}}}}
\]
