OPTICAL TELEVIEWER


Tool design philosophy & applications
The tool generates a continuous oriented 360° image of the borehole wall using an optical imaging system.(down hole CCD camera which records the image of the borehole wall in a prism)

The tool includes one orientation device thus allowing accurate borehole deviation data to be obtained during the same logging run.

The optical televiewer is fully downhole digital and can be run on any standard wireline.

The purpose of the optical imaging tool is to provide detailed, oriented, structural information. Possible applications are :
Fracture detection and evaluation
Detection of thin beds
Determination of bedding dip
Lithological interpretation
