A system where a group of substantially universal pre-manufactured explosive pellet assemblies are provided for on-site forming of shaped charges. That is, a specifically tailored liner may also be separately provided to the worksite/oilfield and combined with any one of the pellet assemblies so as to form a shaped charge having characteristics that are determined by the particular liner used. In this manner, hazardous shipping of fully assembled shaped charges may be avoided while at the same time allowing the operator a full range of shaped charge performance options based on the availability of uniquely tailored performance determinative liners that are also provided to the oilfield location.

1. A method of shaped charge assembly at an oilfield, the method comprising: shipping a container of substantially universal pre-manufactured unlined explosive pellet assemblies to the oilfield; andselecting a specifically tailored charge liner from a group of substantially variable liners; andcombining the selected liner with any one of the assemblies to form a shaped charge having performance characteristics determined by the selected liner. 2. The method of claim 1 further comprising delivering the liner to the oilfield in separate packaging after said shipping of the container of pellet assemblies. 3. The method of claim 1 further comprising: loading a perforating gun at the oilfield with the shaped charge; andloading the gun with additional shaped charges formed from combining selected liners with universal pellet assemblies. 4. The method of claim 3 further comprising deploying the gun into a well at the oilfield for performing a perforating application therein.
