Abstract: A device and method used to image wells and other fluid-carrying tubulars having localized features of interest. The device scans large areas of the tubular first in a low-resolution mode, then identifies areas that contain those localized features with some probability. The device images the identified areas in a high-resolution mode and stores the images for further image processing. The device may comprise two sensors axially spaced-apart on the device, which sensors may be electromagnetic, acoustic, or cameras.

Abstract: A device and method used to image wells and other fluid-carrying tubulars having localized features of interest. The device scans large areas of the tubular first in a low-resolution mode using an ultrasound sensor and in a high-resolution mode using a camera, then identifies areas that contain those localized features with some probability. The device images are stored for further image processing. The two sensors are axially spaced-apart on the device. A computer remote from the imaging device renders a visualization of the tubular and localized features using the optical and ultrasound images.
