Abstract
A method and apparatus for manufacturing any given length of a completion filter assembly is described. An outer perforated jacket is assembled over the filter media, which is itself placed over a coarse support screen or drainage layer. In the preferred embodiment, the drainage layer and outer jacket have end rings such that when advanced through a die are pushed together with the filter media in between to effect a seal of the subassembly. The subassembly can then be placed on a support pipe which is perforated, and if metallic, the end rings are welded to the support pipe to complete the assembly. Optionally, many of the components can be made of materials which lend buoyancy to the assembly so that when it is advanced into a long lateral, it will float to assist in its proper positioning.
