Abstract: A method for measuring the thickness of casing in a wellbore and/or analyzing the inner surface of the cased or non-cased wellbore. The method includes an positioning an untethered logging tool in a drill string, receiving the logging tool in a catcher positioned within the drill string, positioning a plurality ultrasonic transducers with the average distance between the outer surface of the plurality of transducers and an interior surface of the catcher sub being less than 0.8 mm, and moving the drill string and the logging tool toward a mouth of the borehole while transmitting acoustic waves through the catcher sub toward the wellbore casing and receiving acoustic waves back to the logging tool after the acoustic waves interact with the wellbore casing and reflect through the catcher.

Abstract: Disclosed are perturbation signaling systems and methods for use in a downhole well. Such systems can include a downhole tool configured to hang from a wellbore anchoring mechanism. The tool can have or associate with an energy harvesting system, a power management system, a sensing system, and a wireless communication system. A turbine generator can encode signals into flowing fluid through electric load and related changes in hydraulic energy, transmitting information through the fluid. A receiver station positioned at another well location can decode and or relay the signals. Signals can bypass impediments such as noise zones by inducing signals in adjacent parallel well environments such as an annulus. The receiver station can accumulate energy from repeated redundant signaling over time to enhance communication and signal resolution. An additional wireless communication system can receive and/or relay data to a remote location.

Abstract: A well tool includes a deformable liner configured to be positioned within a wellbore. The deformable liner is configured to be deformed radially. The well tool includes a first inflatable packer configured to be positioned within the deformable liner. The first inflatable packer is configured to be inflated while positioned within the deformable liner to deform the deformable liner radially. The well tool includes a second inflatable packer configured to be positioned around the deformable liner. The second inflatable packer is configured to be inflated to an inner wall of the wellbore.

Abstract: A system including a bottom hole assembly and a ram positioned below a barrier of a well and methods for deploying the same are described. The ram is configured to secure the bottom hole assembly at an end of the bottom hole assembly to secure the bottom hole assembly within the well.

Abstract: An apparatus and methods for using and deploying the same within a subterranean zone are described. The apparatus includes a conduit and an expandable mandrel positioned within the conduit. The conduit is configured to be positioned within a subterranean zone. The conduit has an inner surface and an outer surface. The conduit defines an opening extending from the inner surface to the outer surface. At least a portion of the expandable mandrel is smaller than the opening. A longitudinal length of the expandable mandrel is longer than a longitudinal length of the opening. The expandable mandrel, when actuated, is configured to move in a radial direction with respect to the conduit, such that the portion of the expandable mandrel smaller than the opening moves through the opening and extends beyond the outer surface of the conduit.

Abstract: A system and methods of its use are described. The system includes a well tool configured to be positioned within a wellbore. The system includes a sleeve defining an inner volume. The sleeve is configured to secure at least a portion of the well tool within the inner volume while the well tool is positioned within the wellbore. The system includes a hollow member positioned within the inner volume and coupled to the well tool. The system includes a rod positioned within the inner volume and coupled to the sleeve. The rod passes through the hollow member to couple to the sleeve. The rod is configured to move the sleeve relative to the well tool in response to a pressure applied on the rod. The hollow member defines a seat configured to receive the rod to restrict movement of the sleeve relative to the well tool.
