Patent

CA 2471212

Methods and systems for automatically inspecting a wire-wrapped well screen are provided. A camera may capture an image of a portion of the screen including at least two facing edge portions of adjacent wraps of wire defining a slot therebetween. A thickness of the slot may be determined based on the image, for example, by calculating a distance between the facing edge portions. The camera may be moved relative to the screen to measure slot thickness at several sample locations along a length of the screen. The screen may also be rotated relative to the camera to measure slot thickness at sample locations at different angular offset locations around the screen. Slot thickness measured at the sample locations may be analyzed to generate an inspection report that could be supplied to a customer with the well screen.
