Borehole logging winches for 600m and 1200m borehole logging operations. WinchLIM 600 & 1200 The WinchLIM 600 & 1200 provide a powerful yet solution for deep geophysical logging operations of 600 & 1200 m - 1968 & 3937 ft with standard 4 conductor 3/16" cable. An integrated depth measurement system and automated cable spooling simplify the logging procedure. These winches measure the weight on the cable and are capable of securing themselves if the probe gets stuck in the borehole. The safety trigger threshold can be configured.

PDGC50, Photo-Electric density probe. PDGC50: Photo-Electric Density PDGC50 provides a classic triple-spacing sidewall focussed formation density measurement, with the additional advantage of a incorporating a photo-electric effect energy detection window on the medium-spacing detector. The photoelectric effect (Pe) measurement is a reliable indication of the apparent formation atomic number, meaning that formation lithology and an accurate porosity can often be deduced directly from the results given by the probe. When the Pe log results are combined with those obtained from other probes (eg. spectral gamma) a considerable number of specific « heavy » minerals can be identified. A gamma ray source (Cs137, typically 3.7 GBq), is fixed to the lower extremity of the probe during logging. The source capsule itself is supplied separately by a specialist partner. The mechanical side-walling arm provides a caliper measurement, useful for diameter correction purposes and mud-cake evaluation, and a natural gamma log is a lso obtained by means of a scintillation detector located in the uppermost part of the probe body.

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).
