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)

$$ \mathrm{I}_{\mathrm{AH}}=\mathrm{I}_{\mathrm{w}}-\mathrm{I}_{\mathrm{o}} $$
