A sand control device for restricting flow of particles from a subsurface formation into a tubular body within a wellbore, the device being divided into compartments along its length, each compartment comprises a base pipe. The base pipe defines an elongated tubular body having a permeable section and an impermeable section within each compartment, also comprising a first filtering conduit and a second filtering conduit. The filtering conduits are arranged so that the first filtering conduit is adjacent to the non-permeable section of the base pipe, while the second filtering conduit is adjacent to the permeable section of the base pipe.

Fluid filtering device for a wellbore and method for completing a wellbore

Operators manufacture a wellscreen by forming a wire-wrapped screen on a base pipe. Rather than stopping and restarting winding, the desired length of screen is completed along the base pipe, and then the wire screen is segmented into a plurality of screen sections as required for the various zones and details of the implementation. Operators arrange the screen sections relative to one another on the base pipe, which can have different lengths with and without perforations. On the free ends of these separate screen sections, mating split ring components fit around the free ends and the base pipes. Male edges of one split ring component mate to complementary female edges of another to form the end ring around the screen section and base pipe, and longitudinal welds made in seams along the mating edges affix the split ring components together.
