High-density packing is adopted with a gravel-carrying volume ratio up to 96% (12 lb/gal), that is, 1 m 3 fluid should pack 0.96 m 3 gravel. The other is low-viscosity salt water with a gravel-carrying volume ratio of 8–15% (1–2 lb/gal), which can avoid the possible formation damage induced by the high-viscosity, gravel-carrying fluid.
