Abstract
Autonomous wellbore devices with orientation-regulating structures are disclosed, including systems and methods using the same. The autonomous wellbore devices include a wellbore tool, a control structure, and an orientation-regulating structure. The wellbore tool is configured to autonomously perform a downhole operation within a wellbore conduit that extends within a subterranean formation. The control structure is programmed to determine that an actuation criterion has been satisfied and to provide an actuation signal to the wellbore tool. The orientation-regulating structure is configured to regulate a cross-sectional orientation of the wellbore tool while the autonomous wellbore device is being conveyed autonomously within the wellbore conduit. The methods include performing the downhole operation with the autonomous wellbore device, including locating the device within the wellbore conduit, autonomously conveying the device within the wellbore conduit, autonomously regulating the cross-sectional orientation of the wellbore tool, and autonomously actuating the wellbore tool.
