An assembly () for the illumination of a wellbore, pipeline, tank, vessel or other environment wherein light is diffused and transmitted through an optically transparent material and projected in and around a field of view of a camera lens (). A light source is disposed within a cavity at the proximal end () of a cylindrical shaped, optically transparent material. Light from the source is received into the transparent material, diffused, and transmitted to the distal end of the light tube (), where it is projected in front of and around a field of view of a camera. Control of light intensity may be variable, pre-set before operations, or fixed by component design.

Method and apparatus for well bore illumination and inspection

A validation tool () has a central body member () with threaded connections at each end (), as well as a central bore () extending there through. At least one battery powered video camera () or other optical data sensor is disposed along an outer surface of the body member and can be selective activated and de-activated. Optional mirror(s) () are provided to permit optimum viewing of the surrounding environment, while visual images and/or other sensed data is recorded and stored on at least one data storage media. The validation tool can be used for various purposes including wellbore integrity and verification that drilling mud has been fully displaced with completion fluid in a wellbore.
