Calculation Breakdown

  1. Applied FormulaComputes the standard Amott-Harvey wettability index (I_AH from -1.0 to +1.0) of core plugs from spontaneous and forced imbibition tests to classify rock wettability (water-wet, intermediate, or oil-wet).I_{\text{AH}} = \delta_w - \delta_o = \frac{V_{w,\text{spont}}}{V_{w,\text{total}}} - \frac{V_{o,\text{spont}}}{V_{o,\text{total}}}
