ABSTRACT:
A method is provided for determining the wetting preference of particulate solids, for example sand, dispersed in a multiphase liquid medium having a continuous phase and a discontinuous phase, for example a water-in-oil emulsion. A dispersion of the particulate solids and the liquid medium is passed through an electroacoustical cell and the electroacoustical signal is measured for varying solids content. If the signal remains substantially constant this indicates a wetting preference for the continuous phase, whereas if the signal decreases this indicates a wetting preference for the discontinuous phase.
