Pipe base screen
June 26, 2017sand point de-watering spears screen system
June 26, 2017The Pre-Packed well Screen has been integrated with the latest Wire Wrap technology to provide outstanding durability and performance.
This Pre-Packed well Screen assembly consists of an inner perforated base pipe, jacketed by two Wire Wrapped Screens.
The annulus between the two jackets ispacked with a high quality filter media. The gauge of the inner and outer jackets is determined
by the size and type of filter media. The gauge should be equal to half of the smallest diameter of the filter media.
The filter media is chosen based on the formation sands that are to be controlled. The standard filter media used is high quality gravel pack
silica sand, fully curable resin coated reseived gravel pack sand or ceramic beads are also available.
Industrial vibrating machines are used in conjunction with careful loading of the filter media to ensure proper compaction and even
distribution. High intensity light is used during the inspection process of each Pre-Packed Screen. Each assembly is 100% void free.
Pre-Packed Screens are an economical alternative that may be used to complete vertical or horizontal wells when a conventional gravel pack
is not feasible.
