OPTICAL BOREHOLE TELEVIEWER (OBHTV)

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

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
