Abstract: The disclosure presents processes to determine the direction and magnitude of tubing eccentricity along the length of a tube inserted within a borehole. The tubing can be a wireline, a drill string, a drill pipe, or tubing capable of allowing fluid or other material to flow through it. As borehole operations proceed, the tubing can move toward the side of the borehole. This eccentricity can cause excess wear and tear on the tubing, on the casing of the borehole, or on the inner surface of the subterranean formation. The eccentricity can be measured using acoustic signals that are collected downhole covering the azimuthal angles 0° to 360° at a location in the borehole. The collected signals can be filtered, transformed, and analyzed to estimate the tubing eccentricity. Other processes and systems can use the results to obtain cement bond evaluations through tubing and to determine preventative or restorative actions.

Abstract: Systems and techniques of the present disclosure may correct sensed data to account for an offset position of an imaging tool that is deployed in a wellbore. When an imaging tool is deployed at a location that does not coincide with a center point of the wellbore, images generated from acquired data may be distorted as some of image data will be collected at locations closer to a wellbore wall than other image data. Since the resolution of a sensing device varies with distance, the resolution of data collected by a sensing device will vary with distance that separates the sensing device from the wellbore wall. Furthermore, judgments of distance to features of the wellbore wall may also be distorted because of this offset. As such, systems and techniques of the present disclosure are directed to adjust collected image data to correct for both distance and resolution related effects.
