The DIL38 induction conductivity probe generates an electromagnetic field in
the vicinity of the borehole and measures the response of the formations to
this applied field. On both long (ILD) and medium spacing (ILM) receivers
in-phase and quadrature measurements are taken and digitised by the probe
electronics for transmission to the surface equipment. In this way both
formation conductivity and magnetic susceptibility data can obtained, even in
dry or PVC equipped boreholes.
The relatively low operating frequency and the design of the coil array combine
to minimise borehole effects and maximise both depth of investigation and
Lim designs, produces and commercializes measuring instruments and solutions dedicated to drilling.
