Abstract

A tubular is prepared for downhole use to include integrated centralizer feature disposed thereon. Blade elements are disposed about a surface of the tubular. An interconnection, such as a band, connected between the blade elements can be used to wrap them circumferentially about the tubular. The blade elements are then affixed to the surface of the tubular to produce the integrated centralizer features by coating a spray welding material over at least a portion of the plurality of blade elements and over at least an adjacent portion of the surface of the tubular. The blade elements can be hollow vanes or fins so they are collapsible when a restriction is encountered downhole to avoid a stuck pipe situation.
