Sand-control screens (Courtesy of U.S. Filter/Johnson Screens). Wire-wrap screens, the most common design, generallyconsist of a drilled or slotted basepipe with wire filters spaced to retain specific gravel sizes. In early versions, fluids flowed only through openings in the basepipe,so ribs, or rods, were added to form a small annulus for increased flow capacity and to reduce plugging. Prepacked screens are manufactured with high-permeabilityresin-coated gravel between two layers of wire-wrap filter media. Premium-mesh screen designs use a specialized wire-cloth media around a wire-wrap-screen. These screensusually include a shroud with drilled holes for additional protection during installation or have openings designed to reduce erosion caused by sand grains and fineparticles impacting directly on the internal filter media at high velocity.

A type ofsand-control completion in which the gravel pack screen is packed off in an openhole section with no casing or liner to support the producing formation. The openhole interval isoften prepared by underreaming a section of reservoir below the last casing shoe. When the treatment is to be applied on an existing well, a section of casing may bemilled out. Gravel pack
