Optical Imager Tool
High-Definition Borehole Imaging
The Optical Imager Tool is a precision instrument designed to capture high-definition optical images of borehole walls.
Using a finely machined prism and CCD camera assembly, the tool delivers images in a range of horizontal and vertical resolutions, digitised for real-time transmission to the surface.
The resulting image is orientated to North and displayed as an unwrapped image log, enabling detailed structural interpretation.
For optimal performance, the tool should be operated above the water table or in clean, clear fluid.
