OPTV 38 & 52 : Optical Televiewer
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 orientation.
