Sandcontrol horizontal wells were originally dealt with by using standalone slotted liners, screens, and, more recently, proprietary screens. The initial productivity of these completions was usually acceptable, and some were outstanding however, in most appliions, the standalone devices either plugged or cut out (eroded) with time.
Screening/Sizing. Sizing is the general separation of products according to their size. The simplest form of sizing is screening, the purpose of which is to separate minerals or other materials into specific particle sizes to create various final products.
Hooked screens are vital to the sizing and grading required by many mineral, sand and agricultural processes. GDW hooked screens fit separators from leading equipment manufacturers. Quality fabriion ensures maximum screen tension for extended service and optimum production. Mesh sizes range from large oneinch openings to 500 mesh.

Sand production is a problem that affects hydrocarbon production from unconsolidated sandstone reservoirs. Several factors, such as the strength of the reservoir, its lithifiion and cementation and reduction in pore pressure, may cause sand to be separated from the rock and transported by hydrocarbons to the well. Producing sand commonly causes erosion and corrosion of downhole and
