Abstract (en)
[origin: US2010258302A1] A well screen assembly has an elongate base pipe having apertures therein. A filtration layer resides around the base pipe. A drainage assembly resides between the base pipe and the filtration layer. The drainage assembly includes a plurality of elongate risers carried on a mesh. The drainage layer supports the filtration layer apart from the elongate base pipe and defines an elongate passage between the base pipe and the filtration layer that communicates fluid laterally through the drainage assembly.
