A precision wide angle lens and a CMOS camera assembly permit the OPTV38 and
OPTV52 probes to capture a high-definition video image of the borehole wall in
a variety of horizontal and vertical resolutions.
The resulting image data is digitised in the probe and combined with orientation
sensor parameters for transmission to the surface.
The orientated image log provides a wealth of information relevant to a wide
variety of applications. These include fracture detection and analysis, bedding
or foliation dip and direction, lithological characterisation and core sample
Lim designs, produces and commercializes measuring instruments and solutions dedicated to drilling.
