Segment pressing of shaped charge powder metal liners

A shaped charge liner, comprising:

• a plurality of liner segments for a shaped charge configured to perforate a sidewall of a wellbore upon detonation, wherein the plurality of liner segments comprises:
• a tip liner segment comprising a first group of compacted metal powder having a hollow cone shape with a trailing interface end disposed opposite a tip end, wherein the trailing interface end has a larger diameter than the tip end, and wherein the tip liner segment is configured to be disposed in a shaped charge casing of the shaped charge;
• and
• a base liner segment comprising a second group of compacted metal powder having a truncated hollow cone shape with a trailing base end disposed opposite a leading base interface end, wherein the trailing base end has a larger diameter than the leading base interface end, and wherein the base liner segment is configured to be disposed at least partially within the shaped charge casing,
• wherein each of the plurality of liner segments has a distinct density gradient along an axial length of the liner segment, wherein each of the plurality of liner segments are stacked and pressed together to form a single continuous liner, and wherein a variation between the distinct density gradients determines a momentum gradient of the single continuous liner that thereby affects a desired jetting profile through the sidewall of the wellbore upon detonation.
