TUBING ECCENTRICITY EVALUATION USING ACOUSTIC SIGNALS
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.

ADAPTIVE T1/T2 RATIO SELECTION FOR OPTIMAL COMPRESSION
Systems and methods for compressing nuclear magnetic resonance (NMR) data are disclosed. The methods include the steps of selecting a T1/T2 ratio value, inverting a first portion of the echo train data using the selected T1/T2 value, and reconstructing the inverted echo train using the selected T1/T2 value. A quality measure is calculated based on a comparison of the reconstructed echo train to the original echo train. When the quality measure is satisfactory, the NMR data is inverted using the selected T1/T2 value and transmitted to the surface.

ANTI-DISTORTION WORKFLOW FOR BOREHOLE IMAGE RESTORATION
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.

Aspects of the subject technology relate to systems, methods, and computer readable media for determining a parameter of a formation based on withdrawal of an injected tracer solution. A changing concentration profile of a volume of tracer solution that is withdrawn from a formation is measured.
