Abstract: A low friction, dry lubricant impregnated anti-extrusion apparatus for engagement with an annular seal or packer, wherein said packer is used to seal the annular space of a well or pipe bore. The low friction, dry lubricant impregnated anti-extrusion apparatus being designed to generally avoid absorption of the compression setting forces, wherein the compression setting forces are in turn substantially transmitted through the anti-extrusion apparatus to the packer to effect radial expansion of the packer to seal the annular space, while generally preventing the extrusion of the packer at high pressures and avoiding high frictional contact between the anti-extrusion apparatus and an inner surface of the well or pipe bore.

Abstract: A bulge control compression packer having an elastomeric tubular body and a bulge control member to reinforce the tubular body. The bulge control member including interwoven support elements which generally avoid cutting and gouging the tubular body when the tubular body is in a compressed state and further, generally avoid the accumulation of slack about the bulge control member.
