A system for positioning a sensor within a flow path of a wellbore annulus includes a work string extending into the wellbore annulus from a surface location. The system includes a movable arm on the work string, the arm transitioning between a first radial location and a second radial location. The system further includes a bracket coupled to the arm, the bracket being pivotable about a pivot axis, wherein the bracket supports the sensor and transitions the sensor from a stored position to a deployed position.

Systems and methods include an extreme range anchor, having extending assemblies configured to engage a wellbore, for providing a self-centering, reusable anchor location within a wellbore. The extending assemblies include a first set of arms connected to a first brace, a second set of arms connected to a second brace, and a set of footplates. Each footplate in the set of footplates is connected to the first set of arms and the second set of arms. Each footplate includes a fixator coupled to a radially external face and configured to securely engage the wellbore. The system also includes a pull rod rigidly coupled to the first brace and slidably connected to the second brace. Forcing the pull rod in an axial direction shortens a distance between the first brace and the second brace and forces the set of footplates to move in a radial direction toward the wellbore.

A method, apparatus and system for locating external apparatus mounted to a tubular in a wellbore. The identification of apparatus, such as cable clamps, enables other tools in the string to operate more precisely. A computer model is used to locate the apparatus from acoustic images, which images are acquired using a downhole device having an acoustic sensor or acoustic array. The model may be a classifier, which may be machine trained to classify whether an apparatus is present, its location and its orientation. Automating this locating enables very long wellbores to be processed quickly.

A centralizer assembly replaces an existing centralizer of a wireline tool so the tool can be used with smaller casing, such as casing smaller than 6-in. The assembly includes first and second centralizer units that replace the existing centralizer on a mandrel. Each unit has a sleeve that fits in a recess of the mandrel, and each unit has slider blocks disposed together in the recess on opposing sides of a divider on the sleeve. Arms hingedly connected to the blocks on each unit connect together at a joint having a roller for engaging in the casing. On each unit, a common pin is disposed through the slider blocks, and biasing elements on the common pin bias the blocks toward one another with different amounts of bias.

A device for transporting a sensor assembly in a bore comprises a plurality of wheels azimuthally spaced apart around a longitudinal axis of the device. Each wheel presents a radial extremity of the device. The wheels are moveably supported to move between a minimum outer diameter of the device and a maximum outer diameter of the device. An adjustable stop mechanism is configured to pre-set the maximum outer diameter of the device within a range of maximum outer diameters so that the device is configurable for use in a pre-determined range of bore diameters. One or more spring elements bias the wheels radially outwards and are preloaded to provide a radial force to the wheels when at the pre-set maximum outer diameter.
