The gravel pack should ensure that the completed well operates free of sand; thus the particle size of the pack depends upon the particle size of the aquifer. Gravel pack design should be guided by standard sieve analysis. It is evident from the variety of claims made for well screens and gravel packs that further research is necessary.

The gravel pack provides a prefilter to keep fine sand and sediment from reaching the screen and well. This allows the use of a screen with larger openings, improving the flow rate. The packing gravel must be carefully sized or it can get clogged with sediment and block the water flow.

When a gravel pack is first installed, it lacks some steps that make a completed project. When gravel is poured or pumped into a well, it is not settled. There are big spaces, or even voids, between grains. And the pack probably contains fines that will pass ...

The intake consists of a filter pack and screen. The screen allows water to enter the well and, at the same time, minimizes the entrance of filter pack materials. The filter pack is an envelope of uniform, clean, well-rounded sand or gravel that is placed between the formation and the screen. It helps to prevent sediment from entering the well.
