Abstract
A well screen having an internal alternate flowpath for delivering gravel slurry to different levels within a well annulus and a method for assembling same. The screen is comprised of an outer pipe which is concentrically positioned over a base pipe so that an annulus is formed therebetween. Both pipes are perforated along their respective lengths but only part way around their respective circumferences. The respective perforated sections radially align with each other when the pipes are assembled. A plurality of longitudinal ribs isolate the annulus adjacent the perforated sections (i.e. production side of screen) from the annulus adjacent the non-perforated sections (i.e. alternate flowpath side of screen). At least one outlet is provided through the non-perforated section of the outer pipe to provide an outlet from the internal alternate flowpath.
