Abstract:
A shaped charge liner may include an apex portion and a skirt portion extending from the apex portion. The skirt portion may include a body connected to the apex portion, a perimeter spaced apart from the apex portion, and a carbide layer extending between and spaced apart from the perimeter and the apex portion. A shaped charge for creating a perforation hole in a wellbore casing may include a shaped charge liner having at least one material having hardness that is greater than a corresponding hardness of the wellbore casing. The at least one material is configured to bond to at least one of an outer surface and an inner surface of the perforation hole upon detonation of the shaped charge and penetration of the casing by a perforation jet.
