Claim 0:
1. An assembly for subterranean use, comprising:
a delivery tool releasably retaining stored potential energy in an adaptive support mounted thereto such that upon speed regulated relative component movement in said delivery tool said adaptive support is released from said delivery tool to find support in a surrounding tubular, said adaptive support accepting an object thereon for selective occlusion of a passage in said tubular for pressure treatment of a surrounding formation traversed by said tubular, and
a setting tool selectively initiating said speed regulated relative component movement,
wherein:
said speed regulated relative component movement further comprises a changing volume chamber having an opening sized to control flow into or out of said chamber,
said chamber is defined on said delivery tool between a mandrel held stationary by said setting tool and a piston assembly slidably mounted substantially within said mandrel, and
said piston assembly comprises an extending portion that extends through an opening in said surrounding mandrel to allow a setting sleeve on said setting tool to impact said extending portion of said piston assembly.
