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.
Claims4
A method for determining the wetting preference of particulate solids dispersed in a multiphase liquid medium having a continuous phase and a discontinuous phase, comprising:
- (a) dispersing particulate solids in a multiphase liquid medium at varying solid contents;
- (b) passing the dispersion through an electroacoustical cell;
- (c) measuring an electroacoustical signal of the dispersion with varying solids content;
- and
- (d) determining whether the signal remains substantially constant or decreases with increasing solids content, the former indicating that the particulate solids have a wetting preference for the continuous phase, the latter indicating that the solids have a wetting preference for the discontinuous phase.
