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.

Assume you are using dry gravel with a swell percentage of 15% and a shrink percentage of -7%. Plug those values into the calculator and it will tell you that the compaction factor = 1.237. Multiply the 1185 cubic yards by 1.237. 1185 * 1.237 = 1465.9. To complete this job you will need 1465.9 cubic yards of this gravel in loose state volume.

The gravel-pack sand size is determined by multiplying the median formation grain size by 6. This value is the median gravel grain size. With a straight edge, construct the gravel curve so that its uniformity coefficient, C μ, is 1.5. The actual gravel size can be determined by the intercept of gravel curve with the 0 and 100 percentile values.
