OPTICAL BOREHOLE TELEVIEWER (OBHTV)
An optical imaging system generates a continuously oriented 360° image of the borehole wall.
The OBH 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
