Rheology and flow of water-in-oil emulsions in porous media
- Petroleum Recovery Institute, Calgary, Alberta (Canada); and others
The objective of this study was to determine the effects of injected drop size distribution, volume fraction of the dispersed phase, and emulsifier concentration on the flow of water-in-oil emulsions in porous media. Experiments were conducted with a model emulsion system comprising a synthetic mineral oil, deionized water, and a non-ionic surfactant. Bulk rheological properties of the emulsions were measured with a Couette flow viscometer. The drop size distributions were measured from optical micrographs using an image analysis technique. Flow tests were carried out in a sand pack. A microwave attenuation technique was employed to measure in situ water saturation. Experimental data collected in the flow tests included: measurements of pressure drop across the sand pack at different flow rates; in situ water saturation at a fixed location in the sand pack; and changes in the drop size distribution resulting from the flow through a porous medium.
