    Abstract: A tool assembly for performing a wellbore operation including an actuatable tool, a location device, and on-board controller are together dimensioned and arranged to be deployed in the wellbore as an autonomous unit. The actuatable tool, such as a perforating gun having associated charges, perforates a wellbore along a selected zone of interest. The location device, such as casing collar locator, senses the location of the actuatable tool based on a physical signature provided along the wellbore. The on-board controller or micro-processor is configured to send an activation signal to the actuatable tool when the location device has recognized a selected location of the tool based on the physical signature. The tool assembly further includes a multi-gate safety system. The safety system prevents premature activation of the actuatable tool.

    Abstract: Systems and methods for secondary sealing of a perforation present within a wellbore casing associated with a primary sealing agent. The wellbore casing defines a casing conduit present within a wellbore that extends between a surface region and a subterranean formation. The systems and methods include a sealing apparatus that retains a charge of sealing material with a secondary sealing agent and is conveyed within the casing conduit to within a threshold distance of the perforation. The systems and methods further include selectively releasing the charge of sealing material from the sealing apparatus, such as by a release mechanism, to deliver the charge of sealing material to the perforation, to supplement the primary sealing agent (and/or a seal formed thereby), and/or to decrease a flow rate of a fluid from the casing conduit through the perforation.

    Abstract: Remotely actuated screenout relief valves, systems and methods are disclosed herein. The methods include providing a proppant slurry stream that includes proppant to a casing conduit that is defined by a casing string that extends within a subterranean formation. The methods further include detecting an operational parameter that is indicative of a screenout event within the casing conduit. Responsive to the detecting, the methods include providing a flush fluid stream to the casing conduit, opening the remotely actuated screenout relief valve, and displacing the proppant from the casing conduit into the subterranean formation with the flush fluid stream via the remotely actuated screenout relief valve. The methods may further include closing the remotely actuated screenout relief valve. The systems include hydrocarbon wells that include the remotely actuated screenout relief valve and/or hydrocarbon wells that include controllers that are configured to perform at least a portion of the methods.
