Hi-OPTV High Resolution
Optical Televiewer
For borehole logging
The Hi-OPTV provides a continuous very high resolution oriented image of
the borehole walls using a conventional light source. A unique optical
system based on a fisheye lens allows the probe to survey 360 degrees
simultaneously. This information is processed in real time to produce a
complete “unwrapped” image of the borehole oriented to magnetic north.
The probe offers superior resolution to the HRAT acoustic probe and
produces images in real colour. While, unlike the HRAT, it can operate in
air-filled boreholes, it is unsuitable for boreholes containing mud or
cloudy fluids.
Hi-OPTIV applications include:
- Frature
identificaton and orientation
- Stratigraphic
studies
- Local
stress studies (break-out)
- Core
orientation
- Case
hole studies
DIP
Image-processing software:
RG-DIP is sophisticated Windows™- based package for processing,
interpreting and displaying acoustic and optical televiewer image logs
and 4-arm dipmeter logs. Standard log presentations include tadpole and
stick plots, stereographic projections of poles to planes and azimuth
frequency diagrams. The synthetic core display allows convenient
comparison of log and field data for orientation of fractured or
incomplete core sections.
