Abstract

A method and device for a radially expandable downhole tool for bearing axial loads upon radial expansion into anchoring and sealing engagement with a downhole tubular positioned in a subterranean wellbore. The device may comprise a radially expandable tubular defining an interior passageway and an exterior surface. The device may further comprise an axial load bearing assembly positioned on the exterior surface of the expandable tubular and having an anchoring sub-assembly for engaging the downhole tubular and bearing axial loads placed on the downhole tool, the anchoring sub-assembly having a plurality of radially extending ridges, each ridge having a hardened anchoring surface and corners, for penetrating into the downhole tubular and a plurality of longitudinally extending milled grooves formed in each ridge, and a sealing sub-assembly for, after the radial expansion, engaging the downhole tubular and sealing the annulus defined between the downhole tubular and the radially expandable downhole tool.
