Abstract: An assembly (100) 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 (10). A light source is disposed within a cavity at the proximal end (102) 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 (30), 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.

Abstract: A method and apparatus for efficient and effective collection of debris from a wellbore, while permitting simultaneous visual verification of such debris collection. A debris collection assembly comprises a combination of one or more of the following: a reverse circulation assembly, a video assembly and at least one filter assembly. Fluids are circulated into a wellbore annular space via the reverse circulation assembly, into the video assembly where fluid and any associated debris are visually sensed and recorded, into the filter assembly where debris is separated from the fluids and collected, before cleaned fluids are circulated out of the wellbore. The components of the debris collection assembly are substantially modular, and can be run in combination with conventional wellbore cleaning tools (such as, for example, workstring-conveyed brushes, scrapers and/or magnets).

Abstract: A downhole camera assembly (100) comprises a camera having a side-view viewport (82) that can be conveyed and manipulated within a wellbore on flexible cable. Light emitted from a light source is diffused and directed by a transparent or translucent material (61) in a substantially 360-degree pattern within a wellbore, thereby illuminating portion(s) of the wellbore positioned laterally to the camera assembly in a field of view of the viewport. The viewport may be selectively rotated 360 degrees by a motor assembly (40) positioned within the camera assembly which can be controlled from the earth's surface.

Abstract: A method and apparatus for visual inspection of wellbore environments wherein a real-time video feed is received at the earth's surface from a camera assembly positioned downhole within a wellbore. The camera system is capable of recording high quality video images in full streaming quality and speed in either color or black and white bands, simultaneously transmitting live visual images to the earth's surface, and accepting and acting upon commands from the surface (including, without limitation, recording programmability).
