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 !

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.

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.

EM25, Single induction probe. EM25: Single Induction (small diameter) The Slim Single Focused Induction EM25 sonde uses a three-coil focused electromagnetic array to provide a conductivity log . An oscillating high frequency magnetic field from a transmitter coil inside the probe induces an alternating electrical current within the surrounding conductive formation. This current, in turn, induces a voltage within receiver coils in the probe proportional to the formation conductivity. The transmitter-receiver spacings determine the depth of investigation of the measurements. Additional focusing coils minimize the contribution of the borehole signal. The sonde coil spacings are optimized to achieve high vertical resolution and a deep radius of investigation, with minimal borehole influence when logging in conductive-fluid-filled boreholes. The Slim Single Focused Induction EM25 sonde main features are : Formation conductivity measurement in dry or fluid-filled borehole or even in PVC casing Phase detector discriminates between magnetic susceptibility and conductivity signals Natural gamma measurement available for correlation Contact us to get a quote or request more information.

The FTC60 probe provides precise readings of the flow speed of the fluid, the temperature and the electrical conductivity contained in the borehole. FTC60: Temperature/Conductivity/Flow The FTC60 probe provides precise readings of the temperature, electrical conductivity and flow speed of the fluid contained in the borehole. Its main applications are in obtaining groundwater quality and production data in hydrogeological or pollution studies , either on a single or multi-well regional basis. Another possible application is the detection of setting cement by means of the heat given off during this process; for example in a borehole after casing installation and grouting or in quality control of cement piling works. The lightweight impeller and low friction bearing assembly permit this probe to react almost instantly to any vertical movement within the fluid column of a well or borehole. The direction of flow relative to the probe can be determined from the sense of rotation of the impeller. Contact us to get a quote or request more information.

The FWS60 transmits to the surface the full sonic waveform arriving at each receiver during a user-configurable sampling window. FWS60: Fullwave Sonic The advantage of the FWS60 tool is that it digitises and transmits to the surface the full sonic waveform arriving at each receiver during a user-configurable sampling window. For each receiver the user can choose one of three sampling periods to optimise the acquisition according to the application and/or formation characteristics. The sonic waveform data provided by the FWS60 has many applications: these include the determination of formation mechanical properties, fracture analysis, permeability and porosity estimation and cement bond assessment. According to customer preference, the probe can be supplied with three (version 3RX) or four (version 4RX) receivers. Contact us to get a quote or request more information.
