A treatment method used to prevent the production of formation sand into the well-bore.

The objective is to stabilize the formation while causing minimal impairment to well production.

In gravel pack operations, a stainless steel screen is placed in the well-bore and the surrounding annulus is packed with prepared gravel of a specific size. This sand or gravel pack is designed to prevent the passage of formation sand.

The critical aspect is to keep the pack as clean and uniform as possible. For this reason, special tools, materials and pumping equipment are used.
