ABOUT Since 1985 LIM has been recognized internationally as a specialist in instrumentation and measurement, whether during or after drilling (drilling instrumentation and borehole logging). From the beginning, technological innovation has been an integral part of the LIM group's DNA. In terms of INSTRUMENTATION which is its core historical business, LIM SAS offers a wide range of data loggers whether for drilling parameters, in-situ geotechnical tests (Pressuremeter, Penetration tests, Lugeon packer tests) and special foundations processes such as low pressure grouting, jet grouting, bored piles, ... LIM SAS recently completed its range of data loggers with equipment allowing borehole deviation measurement and high precision GPS navigation (RTK) for drilling rigs. Thanks to its GEO-LOG 4 cloud based sofware, LIM offers a solution that automatically transfers and preprocesses data recorded on site. In terms of geophysical BOREHOLE LOGGING, LIM LOGGING , which is the result of the acquisition by LIM of Electromind in 2017, now offers a very complete range of logging probes. At the international reputation level, the OPTV and BHTV televiewers from LIM LOGGING are unanimously considered to be the benchmark products on the market. 1985 Year of creation > 150 Countries > 5 000 Number of equipment sold CUSTOMERS And many others !

3AC, 3 arms caliper. By means of three spring-loaded arms maintained in contact with the borehole wall, the 3AC38 probe provides a representative measurement of the borehole diameter. 3AC38: Three-arm caliper probe By means of three spring-loaded arms maintained in contact with the borehole wall, the 3AC38 probe provides a representative measurement of the borehole diameter. The standard probe nose section and arms provide a high-resolution measurement over the diameter range from 40 to 300 mm. If the supplied arm extensions and nose section extension tube are installed, the upper diameter limit is increased to 700 mm. As an indicator of enlarged zones or fractures, this log is useful both in assessing the competence of the formations and as a basis for calculating environmental corrections for other logging parameters such as fluid flow and production assessment. The basic open-hole diameter log can be integrated over depth to calculate an accurate borehole volume for cementing or gravel-packing operations. The probe is also useful for quality control purposes, for example to verify the depth and diameter of casings and screens installed in a water well. As an option, the probe can be supplied with a natural gamma detector to provide additional lithological information or for horizon corelation purposes.

Trisonde, gamma gamma probe, double density probe, density logging. TRS38G: Trisonde (Density) The TRS38G probe provides long-spaced (LSD) and high-resolution (HRD) 4π global density measurements, based on the Compton scattering principle, as well as a natural gamma log. This probe is intended for use in open and cased-hole conditions where a focussed sidewall density probe can not be deployed, or where calibrated results in g/cm3 are not necessary. It is widely used in the geotechnical sector where boreholes are drilled for reconnaissance, diagnostic or remedial works. Contact us to get a quote or request more information.

GRT38, Gamma ray temperature probe. GRT38: Natural Gamma + Temperature + CCL In addition to its primary role as a lithological or clay indicator, a natural gamma measurement is frequently used as the basis for establishing correlations between boreholes and to ensure accurate depth matching between different logging runs made in the same borehole. For these reasons, many LIM LOGGING probes provide this measurement as an additional log along with other parameters. The GRT38 probe provides a solution for cases where only a basic, total counts natural gamma log is required and also provides a borehole fluid temperature measurement useful for correcting certain other logs. Based on a ø25 x 50 mm NaI(Tl) scintillation crystal detector coupled to a high-performance photomultiplier tube, the probe boasts excellent sensitivity (±1.2 cps / API unit) and provides a high quality final result. For clients requiring this additional parameter, the probe can be factory fitted with a casing collar locator (CCL) detector. Contact us to get a quote or request more information.

IP38, the formations surrounding the borehole are subjected to an alternative square-wave voltage applied via the upper and lower injection electrodes. IP38: Induced Polarisation The formations surrounding the borehole are subjected to an alternative square-wave voltage applied via the upper and lower injection electrodes. Following each injection cycle, the resulting potential difference over a section of the formations is analysed as it decreases with time. The form of this decreases curve is related to the chargeability of the formations. A high chargeability indicates that induced electrochemical potentials are able to develop within the formations as a result of ion transfer between pore fluids and semi-conductive metallic mineral grains present within the rocks. The IP38 probe is particularly suitable for mining exploration in the context of a disseminated sulphide mineralisation. In the hydrogeological domain, it can also provide qualitative information about the permeability of potential aquifer horizons. Contact us to get a quote or request more information.

Solution de mesure LIM pour les travaux souterrains UNDERGROUND WORKS The PocketLim is a recorder that monitors drilling parameters during underground work, particularly tunnel boring. Compact in size, it measures depth, advance speed, hydraulic forces, flow rate, pressure, and other parameters in real time, depending on the context. The recorder and its sensors can be easily integrated into any type of underground equipment, including tunnel boring machines. The MiniLIM was recently installed on a latest-generation Robbins tunnel boring machine, the MDM500 Mine Development Machine - Robbins , which is notable for being the first tunnel boring machine with a rectangular cutterhead. The main parameters recorded are: -Instantaneous advance speed -Pressure on the drilling tool -Impact pressure -Rotational torque -Injection pressure and volume Other parameters can be measured on request.
