Abstract: A pressure actuated packing assembly for use in sealing the annular area of fluid flow devices to provide and maintain an effective, long-term seal therein. The pressure actuated packing assembly is designed for use in chemically hostile environments, and for applications involving temperature and pressure differentials. The pressure actuated packing assembly automatically adjusts for wear, misalignment and service irregularities, while generally reducing the leakage and fugitive emission escape of fluid, flowing therethrough. The pressure actuated packing assembly is preferably constructed of an elastomeric energizer, a circular jacket member having an internal channel to substantially retain the elastomeric energizer and a rigid sealing insert member preferably disposed within the channel of the jacket member.

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.
