Video Borescope has been used to visually record defects such as internal coating blisters in tubular or any internal defect that needs to be viewed for records. Eagle has both fiberscope and rigid recording devices.
Rigid borescopes are similar to fiberscopes but generally provide a superior image. Rigid borescopes have the limitation that access to what is to be viewed must be in a straight line. Rigid borescopes are therefore better suited to certain tasks such as inspecting mud motor stators, drill collars and hydraulic manifold bodies. A flexible borescope includes a bundle of optical fibers which divide the image into pixels. It is also known as a fiberscope and can be used to access cavities which are around a bend.
