1. A holding device comprising:
- a shaped charge holder comprising;
a body comprising a plurality of shaped charge receptacles;
a plurality of retention mechanisms extending from a portion of the body, wherein each one of the plurality of retention mechanisms is configured to retain a shaped charge within a shaped charge receptacle of the plurality of shaped charge receptacles; and
a cavity extending through the body along a central axis of the body, whereineach of the plurality of shaped charge receptacles extends radially from the central axis of the body and the plurality of shaped charge receptacles are arranged in a single axial plane, andeach of the plurality of shaped charge receptacles is configured for receiving the shaped charge in a configuration for directly initiating the shaped charge without the use of a detonating cord.

Abstract
A positioning device includes a shaped charge holder. A plurality of shaped charge receptacles formed in the shaped charge holder are configured to arrange a plurality of shaped charges in a desired orientation. The shaped charges are detonated by a detonator in response to an initiation signal. The positioning device may be secured in a perforating gun module, with vertical and horizontal movement of the positioning being inhibited in the perforating gun module.
