The options include a standalone screen, a gravel pack, a frac-pack, and, in some wells, simply producing below the rate that fails the rock. Chemical consolidation is used less often. The choice depends on how weak the sand is, the grain-size distribution, and whether the completion also needs a fracture to beat the skin.
A screen that is plugged with fines, or a pack with a void, fails either by sanding up or by choking the rate. Sand control is a completion decision made before the well is put on production. Fishing sand out of a pump later is a consequence of not having made it.
