Abstract

According to some embodiments, an autonomous perforating drone for downhole delivery of a wellbore tool, and associated systems and methods, are disclosed. In an aspect, the wellbore tool may be a plurality of shaped charges that are arranged in a variety of configurations, including helically, in one or more single radial planes, or opposing around a perforating assembly section, and detonated in a top-to-bottom sequence when the autonomous perforating drone reaches a predetermined depth in the wellbore. In another aspect, the shaped charges may be received in shaped charge apertures within a body of a perforating assembly section, wherein the shaped charge apertures are respectively positioned adjacent to at least one of a receiver booster, detonator, and detonating cord for directly initiating the shaped charges.
