Placement experiments in a full-scale sandpack model as well as small-scale experiments in a transparent sector model have shown that the placement profile of a high-viscosity (sand-consolidating) fluid is superior to that of a low-viscosity fluid owing to a more stable injection-front during displacement, reduced dilution of the consolidation fluid by the pore fluid, less movement under the influence of gravity after placement, more event placement across zones containing many perforations, and elimination of pore fluid entrapment between different perforations. Experiments have shown that movement of the injected fluids under the influence of gravity can be described by dimensionless groups. Mixing between injected and pore fluid in a porous medium was shown to be independent of injection rate and to decrease with increasing viscosity of the injected fluid. The data discussed in this paper can be used to estimate the effectiveness of sand-consolidation treatments in the field.
