Sand production erodes hardware, blocks tubulars, creates downhole cavities, and must be separated and disposed of on surface. Completion methods that allow sandprone reservoirs to be exploited often severely reduce production efficiency. The challenge is to complete wells to keep formation sand in place without unduly restricting productivity.

The major ingredients are silica sand, limestone, and soda ash. Other ingredients may include calcined alumina, borax, feldspar, nepheline syenite, magnesite, and kaolin clay, among others. Silica sand is used as the glass former, and soda ash and limestone help primarily to lower the melting temperature.
Silicon metal is made from the reaction of silica (silicon dioxide, SiO2) and carbon materials like coke, coal and wood chips. Silica is typically received in the form of metallurgical grade gravel. This gravel is % silica, and is 3 x 1 or 6 x 1 in (8 x 3 cm or 15 x 3 cm) in size.
Continuous fusion: In the continuous method, quartz sand is poured into the top of a vertical melter that consists of a refractory metal crucible surrounded by electric heating elements. The interior is maintained in a neutral or slightly reducing atmosphere that keeps the silica from reacting with the refractory metal.
