Abstract: A formation evaluating system including a sonic sensor device attached to a drill string adjacent to a bit includes a sonic source and a first sonic receiver aligned adjacent to the sonic source, and a second sonic receiver aligned with a horizontal offset X Three kind of two-way trip times are measured: from the sonic source to a) the first receiver after a reflection at the borehole wall, b) the first receiver after propagation in a layer below the borehole wall, an invaded zone, and a reflection at an interface below the borehole wall, and c) the second receiver after oblique propagations in the invaded zone and a reflection at the interface. After determining a sonic speed in the drilling mud and a sonic speed in a matrix of the invaded zone, a porosity and a thickness of the invaded zone are estimated based on a time average equation.

Abstract: A robotic device and method for inspecting a pipeline to assess metal loss, the presence of defects and corrosion effects. The robotic device is an inline inspection tool that can establish a positional address in the pipeline using known positional benchmarks. The robotic device comprises flexible electronic caliper sensors measuring pipe diameter and an elastic foam body to prevent seizing within the pipeline. A removable PCB enables interchangeable operation with in-kind devices of different diameters and/or with the computers, extracting and plotting the data. The method of measurement may use data fusion between different instruments and measurement methodologies.
