A borehole televiewer log is comparable to a picture of a continuous core and may yield even more information since it is a picture of the cores host environment; i.e., the inside of the borehole as it exists in the subsurface. Important relationships are preserved which can be lost when cores are brought to the surface. Fractures, bedding planes, vugs, and lithology changes are identifiable on borehole televiewer logs. The travel time of the signal from the sonde to the borehole wall and back to the sonde recently has been used to form a second log: the transit time log. Interpretation problems due to noncircular borehole and eccentered logging sondes are easily overcome using the combination of amplitude and transit time logs. Examples are given to demonstrate potential use.
