LIM SAS, LIM LOGGING LIM GROUP LIM SAS was incorporated in 1985 near Lyon in France, by Mr. Frédéric Malinet , a geologist. The LIM SAS corporate objects are the design, manufacture and marketing of measuring instruments and software applied to drilling for following purposes, geotechnical, special foundations, drill and blast, mining and hydrogeological exploration. To complete its product offering, on January 1, 2017 LIM SAS integrated Electromind , a company based in Luxembourg and specialized in the development, manufacture and marketing of logging (borehole geophysical) equipment. Electromind became LIM LOGGING. Beyond the simple design of measuring instruments, by offering hardware and software, LIM is positioned as a provider of complete solutions for the measurement and acquisition of drilling data, whether during drilling or in boreholes after their completion. LIM SAS & LIM LOGGING ’s main business areas are Special Foundations, Geotechnics, Hydrogeology, Mining and Extractive Industries as well as Underground Work (Tunnels).

The DIL38 induction conductivity probe generates an electromagnetic field and provide two simultaneous conductivity logs. DIL38: Double 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.

GRS, Gamma Ray Spectral. Able to resolve discrete gamma ray energy levels. GRS42 & 60: Spectral Gamma The detector assembly comprises of a 25 x 50 mm ( GRS42 ) or 50 x 150 mm ( GRS60 ) cylindrical NaI crystal coupled to a thermally stabilised photomultiplier tube. According to type the probe is capable of resolving 250 or 500 discrete gamma ray energy levels over the range 60 to 3 060 keV. Count rates from all of which are transmitted to the surface during logging. Subsequently, discrete windows centred on the characteristic K, U and Th peak levels are used to derive the concentration of these radio-elements.
