Abstract

A positioning device includes a shaped charge holder. A single shaped charge receptacle formed in the shaped charge holder is configured to arrange a single shaped charge in a desired orientation. The shaped charges are detonated by detonating cord in energetic communication with a detonator, in response to an initiation signal. The initiation signal may be electronically communicated from a first perforating gun module to a second perforating gun module without the use of a through-wire. The positioning device may be secured in a perforating gun module, with vertical and horizontal movement of the positioning device being inhibited in the perforating gun module.
