Abstract:
A shaped charge liner may include a plurality of liner segments for a shaped charge configured to perforate a sidewall of a wellbore upon detonation. The plurality of liner segments may include 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. The tip liner segment is configured to be disposed in a shaped charge casing of the shaped charge. The plurality of liner segments may also include 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. The trailing base end has a larger diameter than the leading base interface end, and the base liner segment is configured to be disposed at least partially within the shaped charge casing.
