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

An erosion resistant nozzle is brazed to the surface of a tubular, such as a shunt tube of a wellscreen apparatus, for use in a wellbore. The nozzle is elongated and defines an aperture for communicating exiting flow from the tubular's port. The lead end of the nozzle disposed downstream of the exiting flow can be lengthened to prevent erosion to the tubular. The lead endwall of the nozzle's aperture can be angled relative to the nozzle's length and can be rounded. The nozzle can be composed of an erosion resistant material or can be composed of a conventional material having an erosion resistant coating or plating thereon. Being elongated with a low height, the nozzle can have a low profile on the tubular, and the aperture's elongating can be increased or decreased to increase or decrease the flow area through the nozzle.
