Claims14
A mesh screen apparatus used in subterranean wells, comprising:
- a mesh medium having interlocking layers of mesh material, the interlocking layers being connected by fibers extending from an individual interlocking layer into the next adjacent interlocking layer;
- and
- a base pipe having openings in its sidewall, and onto which the mesh medium is mounted such that the mesh medium covers the openings.
A mesh screen apparatus used in subterranean wells, comprising:
- a mesh medium having a plurality of separate layers of mesh material, the plurality of separate layers of mesh material being interlocked by fibers extending from at least one layer of mesh material into an adjacent layer of mesh material;
- and
- a piece of equipment having at least one intelligent completion device which the mesh medium at least partially encloses such that the mesh medium prevents infiltration of particulates into the equipment.
