Amott-Harvey wettability index
Input(s)
\(I_{o}\): Oil Spontaneous Imbibition Ratio (dyn/cm)
\(I_{w}\): Water Spontaneous Imbibition Ratio \((\mathrm{dyn} / \mathrm{cm})\)
Output(s)
\(I_{A H}\): Amott-Harvey Index (dimensionless)
Formula(s)
\[
\mathrm{I}_{\mathrm{AH}}=\mathrm{I}_{\mathrm{w}}-\mathrm{I}_{\mathrm{o}}
\]
