Optical Televiewer

Using a rotating mirror to image air or water filled boreholes, this high resolution tool has replaced video surveys for many borehole surveys. Typical resolution is 2 millimeters with fracture resolution down to 0.1 millimeter, and radial resolution to 1° depending upon borehole clarity. The output of this tool can be presented as a virtual core. Interpretation typically includes the location and orientation of borehole fractures.
