A precision wide angle lens and a CMOS camera assembly permits a
high definition video image of the borehole wall to be captured in a
variety of horizontal and vertical resolutions. The resulting image is
digitised in the sonde and combined with the orientation data for
transmission to the surface.
The orientated, unrolled image log, whether as a standalone product or
when forming the basis of a detailed structural interpretation, proves
immensely useful in a wide variety of applications. These include core
orientation, fracture detection and analysis, bedding dip and direction,
Lim designs, produces and commercializes measuring instruments and solutions dedicated to drilling.
