DIL38: Dual Induction

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 vertical resolution.
