Endure screen, made of multi-layer sintered woven mesh, is one of the long serving sand control Premium mesh product with long track record: launched in 2003 it has been globally successful used mostly for open hole completions with or without a gravel pack. Known for its higher mechanical properties, reliability and efficiency, Endure lasts longer in extreme conditions.
Multiple layers of sintered woven-wire mesh form the screen filter: three or four layer mesh is chosen based on requirements or to enhance the strength of the mesh, as also a dutch weave or a square weave filter layer is chosen to accomodate the desired pore size. The higher thickness of the filter media helps ensure weld integrity at terminations of the sintered laminate tubes. Sintering the mesh layers increases mechanical stability, which ensures that the filter’s pore openings do not change during installation or production and injection.
The inner drainage layer, acting as standoff, shall ensure uniform flow of oil across the perforated base pipe, while a perforated outer shroud with higher open area ensures protection and high-flow across the outer surface.
