... when compared to viscous polymer systems. The low viscosity brines exhibited complete annular packing with very tight grain to grain compaction. The low viscosity systems also provided good perforation filling without the degree of turbulence necessary for intermixing formation and gravel pack sands...

... ABSTRACT The increased use of sidewall core samples for gravel pack design can lead to the improper selection of gravel pack sand size if analyzed by standard sieve analysis techniques. Sidewall cores, which are obtained from the near wellbore region after drilling, are usually contaminated...
