  • Publication number: 20200018139
    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.

  • Publication number: 20190376775
    Abstract: A detonating cord for using in a perforating gun includes an explosive layer and an electrically conductive layer extending around the explosive layer. The electrically conductive layer is configured to relay a communication signal along a length of the detonating cord. In an embodiment, a protective jacket extends around the electrically conductive layer of the detonating cord. The detonating cord may be assembled in a perforating gun to relay a communication signal from a top connector to a bottom connector of the perforating gun, and to propagate a detonating explosive stimulus along its length to initiate shaped charges of the perforating gun. A plurality of perforating guns, including the detonating cord, may be connected in series, with the detonating cord of a first perforating gun in communication with the detonating cord of a second perforating gun.

  • Publication number: 20190368321
    Abstract: According to some embodiments, a bottom-fire 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 and in one or more single radial planes around a perforating assembly section, and detonated in a bottom-up sequence when the bottom-fire 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.

  • Publication number: 20190368301
    Abstract: A drone conveyance system for deploying drones into an oil or gas wellbore is described. The system includes a platform, a drone magazine, a platform receiver, a conveyance, and a wellhead receiver. A drone magazine contains a plurality of the drones and selectively releases/feeds the drones into the platform receiver. More than one drone magazine, each containing different drone types, may supply drones to the platform receiver such that different drones may be ordered for disposal into the wellbore. The platform receiver prepared the drones to be moved from the platform to the wellhead by the conveyance. The wellhead receiver accepts the drones from the conveyance and prepares each received drone for dropping into the wellbore via the wellhead.

  • Publication number: 20190366272
    Abstract: A detonator positioning device for use with a detonator in a perforating gun assembly is described. The detonator positioning device is configured for electrically contactably forming an electrical connection within the perforating gun housing by contact. The detonator positioning device includes a body having a first end, a second end, and a central bore extending between the first and second ends. The central bore is adapted for receiving one or more electrically contactable components of a detonator. The detonator positioning device aligns at least one of the one or more electrically contactable components to form an electrical connection with a bulkhead assembly.

  • Publication number: 20190330947
    Abstract: A detonator activated wireline release tool is provided for use in geological well operations that enables the wireline cable to be easily released from tool string equipment upon activation of a detonator housed within the release tool. The release tool has a wireline subassembly portion that is connected to a tool string subassembly portion during assembly. It is sometimes necessary to disconnect the wireline subassembly from the tool string subassembly at a time when accessing the either is not physically possible. Such release is achieved by sending an electronic signal that detonates an explosive load which actuates a latch through an expansion chamber. The latch shifts and allows the finger flanges previously connecting the subassemblies to disengage, thus releasing the subassemblies.
