Abstract
A system and method using liner joints, pup joints, couplings, or similar components incorporating a mechanically-induced weak point to access targeted subterranean rock formations. More particularly, the mechanically-induced weak point may comprise a machined weakness, blow-out plug, burst disc, soluble plug, or the like. The mechanically-induced weak point may be adapted to burst at a predetermined blow-out pressure differential. Alternatively, the soluble plug may be manufactured of soluble material adapted to selectively dissolve in certain solutions.
