Abstract
An apparatus comprises a first cluster of perforator guns positioned circumferentially around a central longitudinal axis at a first axial position, wherein the first cluster is configured in a closed position while the apparatus is being lowered to a perforator position in a wellbore. After the apparatus is lowered to the perforator position, the first cluster is to move to an expanded position such that the perforator guns are moved closer to a target that is to be perforated.
