Abstract

A shaped charge closure member for encapsulating a slotted shaped charge is described. The closure member includes a body having a closed upper portion, and a lower portion opposite the upper portion. The closure member has first and second side walls, a front wall, and a back wall. Each wall tapers from the lower portion to the upper portion. A skirt having a substantially rectangular cross-section extends vertically away from each of the walls, at the lower portion of the body. The skirt engages with an open portion of a slotted shaped charge case, thereby forming an encapsulated slotted shaped charge. The encapsulated slotted shaped charge may be used in an exposed perforating gun system.
