The average sand size varies from production well to another, even in the identical formation, however; typical sand particle sizes are within the range of 50–150 μm. Moreover, sand particles concentration is changing from time to time (every 24 h) at the same well, and even at a good completion job, a sand prone well might yield 5 ppmv …

Well preparation for gravel packing

Gravel-pack completion fluids must be sufficiently clean in order that suspended particles do not plug or reduce the permeability of the formation, perforations, or gravel-pack sand. To achieve a clean fluid requires filtration. Completion fluids are typically filtered to 2 or 10 microns, but in some cases, they are filtered to 1 micron.

In the sand-pack test, the sand is placed directly on the screen with a confining stress imposed on the sand, so the sand will be in full contact with the screen. A wetting liquid will then flow through the sand pack and the screen. This test measures the weight of sand produced as well as the pressure drop that occurred during the test.

Sand vs. Gravel for Backfill: Which Is Right for Me?

Sand holds its shape well. Laying down sand as a backfill requires water, as you need to keep it wet to help it compact properly. Once it dries out, it becomes very solid. Not that you could build a skyscraper with it, but once sand dries in place as backfill, it offers a hard mass that won't move around much at all. Cons of Sand Backfill
