Abstract
Expandable packers and methods of using same are described. The expandable packers include an anti-extrusion layer comprising a fibrous layer having a first surface adjacent an outer surface of an inner expandable elastomeric member, and a cable layer adjacent the fibrous layer, the cable layer comprising a plurality of stacked unidirectional layers of cables. The cable layer is adapted to form a barrier substantially devoid of gaps through which the inner elastomer member would otherwise extrude into upon expansion of the inner elastomeric member. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
