Abstract
A method and apparatus for determining the extent of defects in tubular elements for use in an oil or gas well is disclosed. The apparatus includes an electromagnetic or other suitable inspection device, cooperating with longitudinal and circumferential position detectors for determining the position and configuration of all defects within a tubular member. Signal generating means are provided for producing signals corresponding to the configuration, longitudinal position, and circumferential position of the defects located within the wall of the tubular member. The signals are processed, preferably by a computer, so that the presence, nature, and precise location of each defect is determined and visually displayed at a suitable display means. Display means are provided for generating a two-dimensional visual display wherein the circumferential and longitudinal positions of the defects are selectably displayed.
