Abstract: A method of manufacturing a base pipe for use in horizontal well completion, the method includes wrapping an inner shroud around a base pipe, the inner shroud is disconnected from the base pipe and forms seams along each edge of the inner shroud; fusing the seams together; allowing the inner shroud to cool, the inner shroud shrinks around the base pipe to form a friction lock between the base pipe and the inner shroud; laying a filter medium onto an outer shroud, wherein the filter medium is disconnected from the outer shroud, thereby creating a mesh filter medium/outer shroud sheet; wrapping filter medium/outer shroud sheet around the inner shroud, the filter medium is positioned between the inner shroud and outer shroud, thereby creating a second set of seams; and fusing the second set of seams together, thereby creating a second friction lock between the outer shroud and the inner shroud.

Abstract: An elongated shroud includes a perforated exterior surface, having rows of holes extending into an interior of the elongated shroud; each row of the have holes of a same width; and the width of the holes associated with each row decrease in each row out from a center row of holes.

Abstract: An apparatus for filtering well fluids and method of manufacture is disclosed. The apparatus comprises an inner support, a filter spirally wrapped around the inner support, and an outer support wrapped around the filter enclosing the filter between the inner and outer supports. The filter has longitudinal edges which overlap and the filter is held in place by friction with the inner and outer supports. The method of manufacturing the apparatus comprises continuously and simultaneously wrapping a filter and outer support around an inner support and disposing the filter between the outer and inner supports.
