Abstract

A method to remove well bore fluid from the path of a shaped-charge jet in order to reduce the effect it has on the jet tip. A precursor liner (70) and a primary liner (50) are both pressed in the same housing (12). The primary liner (70) is similar or equivalent to a standard big hole shaped charge liner. The precursor liner (70) is pressed into the apex end (54) of the primary liner (50) and upon detonation is intended to form an initial very fast moving precursor jet to open a path through the fluid of the well bore annulus for the following primary jet.
