This paper describes an alternative technology to conventional wire wrapped and prepacked screens. In this new screen, multiple and independent layers of a permeable stainless steel composite material are sandwiched between a perforated base pipe and an external armored cage.

Advantages of this design include: 1) even extreme mechanical deformations do not affect the screen's sand retention; 2) an all-metallic construction eliminates the deficiencies common to prepacked screens (loose sand packing, eccentric prepack annulus, chemical incompatibilities with resin coatings, cracking of resin coated prepacks); 3) its compact construction results in a small OD that extends its range down to small diameters for through tubing gravel packs and gravel pack repairs.

These advantages have been substantiated by laboratory tests and field installations. The results of these tests are presented in this paper.
