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.

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.

The BHTV42 acoustic imaging probe or acoustic televiewer with casing thickness option is used to measure the thickness of a drill casing. It uses a rotating transceiver mounted at the lower end of the tool, which sends a beam of highly focused ultrasonic pulses towards the borehole wall (up to 360 times per pulse). BHTV 42: Televiewer Acoustic Wall Imaging. Casing Thickness option BHTV 42: Casing Thickness option The BHTV42CT builds on the industry-reference BHTV42 standard acoustic televiewer probe by adding a casing thickness measurement for cased-hole inspections. As well as recording the primary echo from the inner casing surface, the subsequent parts of the signal returning to the probe are analysed for the repeating signals corresponding to the energy being re-emitted after having traversed the casing itself in both the outward and inward directions.
